Cause
The program is correct in ST grammar but an error
occurs due to device specifications, etc.
Example 1: TS0 := TRUE;
The number of characters used is greater than the
preset maximum value.
There is the following error example that uses
characters greater than the maximum value.
Example 1: Character string label: Str1
Str1 := "123456789012345
678901234567890
123";
When the number of character string
characters is 33
An illegal device or a numeric value outside the
range is used.
Example 1: M0 := COUNTER_M(TRUE, CC2, -1);
The device other than the timer is used in the
argument of TIMER_M.
Example 1: TIMER_M(X0, CC0, 2);
The device other than the counter is used in the
argument of COUNTER_M.
Example 1: COUNTER_M(X0, TC0, 2);
Corrective Action
Check the contents of the
list displayed in the error
message, and correct the
program.
Change the character
string to within 32
characters.
Correct the device or the
numeric value to within the
