The following table provides a comparison between the CS1W-PRM21/
CJ1W-PRM21 PROFIBUS DP-V1 Master Units and their predecessor, the
PROFIBUS DP Master used in a CS-series PLC
C200HW-PRM21
C200H Special I/O Unit
• CPU Rack,
• C200H I/O Expansion Rack,
• CS-series Expansion Rack
Can not be mounted on a CS1D PLC
0 to F (Hex)
16
2,000 to 2,004 + (10 x unit number)
Up to 4 CIO words contain:
• Command settings
• Unit Status and error flags
• Error reporting from the PROFIBUS inter-
face
D20000 to D20017 + (100 x unit number)
The area contains user defined memory
mapping of I/O data. At start up this area is
transferred to the Unit
Maximum total size: 300 words per Unit
I/O Data words can be allocated to up to 2
input areas and 2 output areas
I/O size per area: up to 200 words
Mapping / area size set in DM words:
CIO: CIO 0000 to CIO 0235
CIO: CIO 0300 to CIO 0511
CIO: CIO 1000 to CIO 1063
HR: HR000 to HR099
DM: D00000 to D05999
Default mapping (DM words contain 0000):
• Output area: CIO 0050 to CIO 0099
• Input area: CIO 0350 to CIO 0399
• Diagnostic flags: CIO 0200 to CIO 0215
Message communication using IOWR and
IORD PLC instructions:
• IOWR to send Global-Control command
• IORD to read slave diagnostics
FINS message communication not sup-
ported
CS1/CJ1W-PRM21 (Unit version 3.0)
CPU Bus Unit
• CPU Rack,
• CS/CJ-series Expansion Rack
CS1W-PRM21 can be mounted on CS1D
0 to F (Hex)
16
1,500 to 1,524 + (25 x unit number)
Up to 25 CIO words contain:
• Command settings
• Unit Status and error flags
• PROFIBUS status and error flags
• Slave status flags
D30000 to D30099 + (100 x unit number)
Not used on the Unit. Reserved for future
use
Maximum total size: 7168 words per Unit
I/O Data words can be allocated to up to 2
input areas and 2 output areas
I/O size per area: up to 7168 words
Mapping and area size set by configurator:
CIO: CIO 0000 to CIO 6143
WR: W000 to W511
HR: HR000 to HR511
DM: D00000 to D32767
EM: E00000 to E32767 (Banks 0 to C)
Default mapping: Not supported
Note Diagnostics flags: available in allo-
cated CIO Area words
FINS message communication. Commands
supported:
• MEMORY AREA READ to read slave
device diagnostics message
• ERROR LOG READ, to read the Unit's
error log
• ERROR LOG CLEAR to clear the Unit's
error log
• RUN to enable communication with a
slave device
• STOP to disable communication with a
slave device
• PROFIBUS MESSAGE SEND to send
messages over PROFIBUS network
(Implemented as of Unit version 2.0).
• EXPLICIT MESSAGE SEND to send CIP-
based messages over the PROFIBUS
network to OMRON slave devices (imple-
mented as of Unit version 3.0)
