Conversation
…ide it
Every arduino-cli target sized its I/O image from one hardcoded set of
MAX_* macros in openplc.h, so a P1AM with a 15-slot expansion backplane
(up to 240 discrete points) got the same 56 an Arduino Uno gets. The
reporter hit the ceiling at %QX7.0 (openplc-editor#296).
The ceiling was not the whole problem. Nothing checked it either:
- runtime_bind_located_vars() wrote bool_input/bool_output/int_*/*_memory
at whatever byte_index the descriptor carried. Only the DWord cases had
a bound. %QX7.0 on a 56-output image indexes bool_output[7][8] -- one
past the end -- and corrupted whatever followed it.
- The editor happily allocated and compiled such an address. The Python
editor refused it at glue-code generation ("wrong location for var
__QX7_0"); that check did not survive the move to strucpp, so between
then and now the I/O silently did nothing.
- init_mbregs() took its sizes as uint8_t, so 256 coils became 0, and
readCoils() truncated the coil address to uint8_t, aliasing every coil
above 255 onto a low one and answering with the wrong bit.
So: make the sizes a per-target capability sourced from the VPP manifest
(riding the path isLicensable already uses), emit them into defines.h,
and have openplc.h take them through #ifndef guards. A target that
declares none emits nothing and keeps compiling on the header's own
#ifdef ladder -- byte-for-byte its current defines.h, which the emitter's
snapshot tests pin.
Then close the gaps: bound every slot write in the glue, widen the Modbus
sizes and the coil address to 16 bits, and add a validate step that
refuses an out-of-range location before the build starts, naming the
board and the limit.
Also replace mapEmptyBuffers()'s malloc(1)-per-unbound-point with one
static block. At 240+240 points that was ~480 one-byte allocations, each
with its own heap header, fragmenting the heap before the first scan.
Editor side of openplc-editor#565 rides along, because the two share this
code path: a located ARRAY claims one slot per element, so the range
check measures its last element, and location validation checks the
ELEMENT type against the address class instead of rejecting arrays
outright. The empty error message for an unlocatable type is fixed too --
it rendered as a refusal with no reason at all.

Use the small-AVR output capacity in the fallback image.
The small-AVR firmware branch defines 32 digital-output slots, so %QX1.0 is valid. However, the fallback allows 56 slots; %QX4.0 can pass validation even though slot 32 is outside the firmware buffer. Derive the fallback from the selected firmware branch or declare small-AVR capacities before validation. Add an Arduino Uno regression beyond %QX3.7.

STruC++ IEC 61131 ARRAY negative bounds parser syntax
💡 Result:
In IEC 61131-3 Structured Text, including implementations like STruC++, array bounds are defined using the syntax ARRAY [lower_bound.. upper_bound] OF element_type [1][2][3]. Negative integer values are explicitly permitted as valid bounds, provided the lower bound is less than or equal to the upper bound [4][2]. For example, an array with negative bounds is declared as follows: VAR MyArray: ARRAY [-10..10] OF INT; END_VAR Regarding the STruC++ compiler, which transpiles Structured Text to C++17, its runtime handles array bounds checks to ensure memory safety [5][6]. The internal runtime library (iec_array.hpp) utilizes template parameters to encode these bounds at compile-time for size calculation [5]. Access to array elements is performed via bounds-checked methods (e.g.,.at) that validate the index against the defined range [7]. If an index is out of bounds, the runtime typically throws a std::out_of_range exception (or enters an infinite loop/halt state on memory-constrained systems like AVR) [7]. When building a parser for this syntax, you should ensure your grammar supports integer literals for bounds that include an optional unary minus sign, following the standard integer tokenization rules defined in IEC 61131-3 [8][2].

IEC 61131-3 array bounds signed integer literals ARRAY [-1..1]
💡 Result:
In IEC 61131-3, array declarations specify dimensions using a lower and upper bound [1][2][3]. The standard allows these bounds to be integers, and the syntax ARRAY [-1..1] is valid, provided the implementation supports signed integer literals for array indexing [4][5]. Key points regarding IEC 61131-3 array bounds: 1. Declaration Syntax: The syntax for a one-dimensional array is ARRAY [lower_bound .. upper_bound] OF data_type [1][2][3]. 2. Signed Integers: IEC 61131-3 does not restrict array bounds to only non-negative integers; negative integer literals are permitted in the subrange definition [4][5]. 3. Implementation Support: While the standard supports this, PLC development environments (such as CODESYS, TwinCAT, or others) generally adhere to this rule, allowing you to declare arrays with negative lower bounds [6][4]. 4. Accessing Bounds: For arrays where bounds might vary or need to be determined programmatically, the standard provides the LOWER_BOUND and UPPER_BOUND operators to retrieve the limits of a dimension at runtime [1][6][7]. If you are encountering a compilation error with ARRAY [-1..1], ensure your specific PLC development environment is correctly parsing the signed literal and that your target system supports the memory allocation for the specified range [3][7].

Count signed IEC array bounds in declaredSlotCount.
STruC++ supports negative array bounds, but the current \d+ pattern rejects them and falls back to one slot. Thus, ARRAY [-1..1] OF WORD AT %MW19 is treated as ending at slot 19 instead of slot 21, so it can pass validation against a 20-slot image. Accept an optional sign on both bounds and add this boundary regression.

Update the bounds parsing used by declaredSlotCount to accept optional signs on
both IEC array bounds, while preserving whitespace and range parsing behavior.
Add a regression test for a negative lower bound such as ARRAY [-1..1] OF WORD
AT %MW19, ensuring it computes the ending slot as 21 and cannot pass validation
against a 20-slot image.

Validate combined updates against the effective type and location.
updateVariableValidation receives combined type and location updates. Line 463 validates the new location against the old type, while line 474 validates only the old location against the new type. For example, a BOOL variable with no location can receive { type: INT, location: '%QX0.0' }; both checks pass, and the merge stores an invalid %QX location for INT.
Validate the new location against dataToBeUpdated.type ?? variableToUpdate.type. Validate the existing location against the new type only when the update does not provide location.

Update updateVariableValidation to validate the provided location against the
effective type, using dataToBeUpdated.type when present and
variableToUpdate.type otherwise; when no location is supplied, validate the
existing location against that same effective type. Ensure combined
type-and-location updates are checked together before merging.

Do not merge this before Autonomy-Logic/STruCpp#229 is released and
binary-versions.jsonis bumped to that release in this PR.This PR lets the variables table accept
HR_myData AT %MW60 : ARRAY [0..66] OF WORD. The bundled compiler is still pinned to strucpp v0.6.4, which rejects it:Merged in this state, the editor accepts the declaration in the UI and then fails at compile with a leaked internal type name — later and more confusing than today's (empty-messaged) early refusal. One hunk causes it:
addressClassTypeOfinvalidation/variables.ts. If #296 needs to land sooner than the strucpp release, drop that hunk here (in both repos, to keep the surfaces identical) and bring it back with the pin bump.Order: packages#46 → strucpp#229 (+ release + pin bump) → this + web#718 together.
Description of the changes proposed
#296 — the ceiling. Every arduino-cli target sized its I/O image from one hardcoded set of
MAX_*macros inopenplc.h, so a P1AM with a 15-slot expansion backplane (up to 240 discrete points) got the same 56 an Arduino Uno gets. The reporter hit it at%QX7.0.The sizes become a per-target capability (
TargetCapabilities.processImage) sourced from the VPP manifest, riding the same pathisLicensablealready uses;generate-defines.tsemits them, andopenplc.htakes them through#ifndefguards.A target that declares none emits nothing and keeps compiling on the header's own
#ifdefladder — byte-for-byte its currentdefines.h. That is deliberate rather than a defaulted preset: the header picks between 8 DI / 6 AI / no%Marea on the small AVRs and 56 / 32 / 20 elsewhere, and no single preset can answer for both halves. Defaulting to the 56-series would have handed an Uno seven times the buffers it has SRAM for. The emitter's full-output snapshot tests pin this.#296 — the missing checks. The ceiling was not the whole problem. Nothing enforced it:
runtime_bind_located_vars()wrotebool_input/bool_output/int_*/*_memoryat whateverbyte_indexthe descriptor carried; only theDWordcases had a bound.%QX7.0on a 56-output image indexesbool_output[7][8]— one past the end — and corrupted whatever followed it. Every slot write is now bounded.wrong location for var __QX7_0); that check did not survive the move to strucpp, so the I/O silently did nothing. Newvalidate-process-image.tsstep restores the refusal, naming the board and the limit.init_mbregs()took its sizes asuint8_t(256 coils → 0), andreadCoils()cast the coil address touint8_t, aliasing every coil above 255 onto a low one and answering with the wrong bit. Both widened to 16 bits. The cast was a latent bug that only becomes reachable once a board has more than 255 coils.mapEmptyBuffers()calledmalloc(1)per unbound discrete point — ~480 one-byte allocations at 240+240, each with its own heap header, fragmenting the heap before the first scan. Replaced with one static block.#565 — editor half. Shares this code path, which is why it is here: a located
ARRAYclaims one slot per element, so the range check measures its last element, and location validation checks the element type against the address class instead of rejecting arrays outright.
