CL300 controller acting as PST
The CL300 controller permits a central processing unit to have maximum
configuration; it is therefore not necessary to specify the CPU number
within the coordination marker.
When the Siemens format is observed, the coordination marker has the
following appearance:
15 7 4 3 0
Word address 0 Bit number
Where: bit number - 0...15
word address - 0...254
word address 0, 2, 4 ... 254
PC600 controller acting as PST
The PC600 controller permits a central processing unit to have maximum
configuration; it is therefore not necessary to specify the CPU number
within the coordination marker.
When the Siemens format is observed, the coordination marker has the
following appearance:
15 7 4 3 0
Word address 0 Bit number
Where: bit number - 0...15
word address - 0...255
word address 0, 1, 2, 3 ... 255
Siemens CP524/CP525 controller acting as PST
When these Siemens controllers are used as a PST, the coordination
marker (CM) contains information on the CPU number, the CM byte and
the CM bit;
- Byte number of the CM: If no CM is used, FFH must be in this location;
the byte number must be within the range of 0-223 for the CP524 and
CP525;
- Bit number of the CM: If no CM is used, FH is in this location;
- CPU number: If the number of the respondent CPU is indicated as a
number between 1 and 4;
If no CPU number, but a CM, is indicated, 0H is in this location;
If no CPU number and no CM are indicated, FH is in this location;
In both cases all CPUs are possible for the partner.
