C200Hw-Prm21 Notes - Omron SYSMAC CS Series Operation Manual

G-1 Introduction
This appendix contains notes on the use of the C200HW-PRM21 PROFIBUS DP Master unit on a CS1 PLC
System. The C200HW-PRM21 is a special I/O Unit, originally designed for the C200H-series PLC, but can also
be used on the CS1-series PLC systems.
G-2 Word allocations
This section provides a brief overview of the memory allocations required by the C200HW-PRM21 for Unit set-
tings and Control and status words. For more details refer to the C200HW-PRM21 PROFIBUS DP Master Unit
Operation Manual (W349-E2-@).

Unit Settings
The Unit settings are located in the DM area in the PLC memory. The exact location of the block of settings
depends on the Machine Number setting, as set prior to power-up on the front of the Unit using the rotary
switch.
The Unit settings define
• the I/O mapping areas and the mapping of the slave status data,
• the data exchange procedure (synchronous or asynchronous)
• the Units behaviour in case of a fatal PLC error (CLEAR or HOLD outputs)
The Unit can be operated in a default mode, i.e. all DM settings set to 0000. The table below lists the contents
of the Unit settings.
