Hello,
I am making conversion from S5 to SLC. I have only upload from PLC. Previous programer used function block FB120 and FB125.
Problem is that i don't know what this programs in fact are doing.
FB125 is called like that:
A I 32.6
JC FB 125
NAME: LEIM
EING: I 32.7
ZIMP: I 64.7
ZAEH: C 36
WERT: KF +50
AUSG: F 36.1
ZEIT: T 37
KONS: KT 030.1
***
The body of FB125 consistes of instructions:
AN =EING
LW =KONS
SD =ZEIT

A =ZIMP
SSU =ZAEH

A =ZEIT
RD =ZAEH

L =ZAEH
LW =WERT
>=F
= =AUSG

So it means:

AN =I 32.7
LW =KT 030.1
SD =T 37

A =I 64.7
SSU =C 36

A =T 37
RD =C 36

L =C 36
LW =KF +50
>=F
= =F 36.1
I can't find out what SSU (something with counter) and RD (probably reset) means.
Can somebody help me?
