Coupling for SPS and PLC
General control telegram: (commands)
Slave
address
(1 byte)
Wordwise presetting of commands:
Slave
address
0x01-0xfe
For example, wordwise presetting (commands):
Slave
address
0x01
0x01
0x01
0x01
0x01
Note:
You can only specify commands with FC 6 or 16 because this is a number, not
bit-coded data. This means that only one command can be executed per
transmission.
For example, for bitwise presetting via function block (PLS-DIn 1-16):
Slave address
0x01
0x01
0x01
