The selector of the CASE instruction must be INT-type.
Ensure that the selector is an integer or bitstring data type (DINT, DWORD, for example).
4265
Number expected after,
In the CASE selector list, another selector must be specified after a comma.
4266
At least 1 instruction required.
Enter an instruction, at least a semicolon.
4267
A function block call must start with an instance name.
The identifier in the function block call is no instance. Declare an instance of the required
function block, or use the name of an instance that has already been declared.
4268
Expression expected
Enter an expression at this position.
4269
END_CASE expected after ELSE branch
Complete the CASE instruction with an END_CASE after the ELSE branch.
4270
CASE constant %ld already in use
A CASE selector must be used once only within a CASE instruction.
4271
The lower limit of the specified range is greater than the
upper limit.
Correct the selector range limits so that the lower limit is not greater than the upper limit.
4272
Parameter
call!
If the function parameters within the function call are specified with parameter names, the
position of the parameters (sequence) must match that in the function definition.
4273
CASE range
range
Ensure that the selector ranges specified in the CASE instruction do not overlap.
4274
Multiple ELSE branch in CASE instruction
A CASE instruction must not contain in excess of one ELSE branch.
4300
Jump or Return require a Boolean input
Ensure that the input for the jump or the Return instruction is a Boolean expression.
4301
Organization unit
inputs
The number of inputs does not match the number of VAR_INPUT and VAR_IN_OUT variables
specified in the organization unit definition.
4302
Organization unit
outputs
The number of outputs does not match the number of VAR_OUTPUT variables specified in the
organization unit definition.
4303
Replace
4320
Non-Boolean expression
The switching signal for a contact must be a Boolean expression.
4321
Non-Boolean expression
The output variable of a coil must be BOOL-type.
4330
Expression expected at input EN of organization unit
Assign the input EN of organization unit
4331
Expression expected at input
unit
The input of the operator organization unit is not assigned.
4332
Expression expected at input
The input of the organization unit is VAR_IN_OUT-type and not assigned.
4333
Identifier expected in jump
The specified jump target is no valid identifier.
4334
Expression expected at jump input
Assign the jump input with a Boolean expression. If that is TRUE, the jump is executed.
4335
Expression expected at Return input
Assign the input of the Return instruction with a Boolean expression. If that is TRUE, the
return is executed.
4336
Expression expected at output input
Link the output with the expression that can be assigned to this output.
4337
Identifier expected for input
Insert a valid expression or identifier in the input box.
4338
Organization unit
None of the inputs of operator organization unit
4339
Incompatible types at output: Cannot convert
The expression in the output box is not type-compatible with the expression it is to be
assigned.
4340
Jump requires a Boolean input
Ensure that the input for the jump is a Boolean expression.
4341
Return requires a Boolean input
Ensure that the input for the Return instruction is a Boolean expression.
4342
Input EN of the box requires a Boolean input
Link the EN input of the organization unit with a valid Boolean expression.
4343
Constant assignment: Impermissible type for parameter
You declared input
assigning it an expression in the dialog Parameters that is not type-compatible.
4344
S and R require Boolean operands
Insert a valid Boolean expression behind the Set or Reset instruction.
4345
Impermissible type for parameter
Cannot convert
You assigned an expression to input
type-compatible.
4346
An output must not be a constant
The target of an assignment must be a variable or direct address with write access.
4347
VAR_IN_OUT parameter requires write-accessible variable
Write-accessible variables must be transferred to VAR_IN_OUT parameters as these can be
modified within the organization unit.
4350
An SFC action cannot be called from outside
SFC actions can be called only within the SFC organization unit within which they have been
defined.
4351
Step name is no permissible identifier:
Rename the step, and select a valid identifier for the name.
4352
Permissible step name :
characters
Delete the impermissible characters in the step name.
4353
Step names used twice:
Rename one of the steps.
4354
Jump to undefined step:
Select an existing step name as the jump target, or insert a step with the as-yet undefined
name.
4355
A transition must not have any side effects (assignments,
FB calls etc.)
A transition must only contain a Boolean expression.
4356
Jump without valid step names:
Use a valid identifier as jump target.
4357
IEC library not found
Check whether the library iecsfc.lib was integrated into the Library Manager, and whether
the library paths specified in the project options are correct.
