A symbol is recognised as a PLC elements when the plc byte wildcard is found for the byte number. The byte number is attached to the wildcard plc byte (Text2 of the parameter block) by the user. This is easiest when loading the symbol or via Change / Symbol parameters.
Note
The designation X may consist of several characters such as E or A or CH.
In order for the Automatic to distinguish these pins from the standard connections such as the power supply which may also have pin names, the following rules must be obeyed:
Rule 1
Any separator for separating between the byte number and bit number. In this case, the byte number must only consist of numbers, the text in front of the byte number must not have any numbers and the bit number must always be the last number. The bit number can be hexadecimal but the byte number cannot. Example: E2.5 or E 2.5 or E 2.A
Rule 2
Byte numbers and bit numbers may also be hexadecimal. In which case, there must be at least one space before the byte number.
Example X AF or X 1CA.
An (invisible) wildcard is assigned to each input or output. When a PLC list is read in or when a comment text is entered, the text is automatically placed at the position of these wildcards. The plc text wildcards must still be supplemented by the bit number of the input or output which has been assigned, from 0 to 7 or 0 to F.
Example |msps-text2 > |msps-textA >
Caution
A text cannot be assigned if there is no wildcard. The wildcards should be General text and not Free text. General text is used for the comment text and symbol text in any case. The length of this is limited to 48 characters.
