CompoBus/S master functions

Remote I/O devices can be allocated up to 256 I/O points (128 inputs and 128 outputs) in input area IR 020 to 
IR 027 and output area IR 030 to IR 037.
• The node numbers can be set to 0 to 7 (128-point mode) or 0 to 15 (256-point mode).
• The communications mode can be set to high-speed mode (max. length 100 m) or long-distance mode 

(max. length 500 m).

DeviceNet slave functions

Up to 64 words (32 input words and 32 output words) can be allocated to the DeviceNet master's I/O. 
The master's I/O can be allocated to the following data areas:

IR 000 to IR 049
IR 200 to IR 227
DM 0000 to DM 2047
LR 00 to LR 15
HR 00 to HR 19
AR 00 to AR 23 (3G3RV-P10ST ' master; read-only)
TC 000 to TC 255

• Explicit message communications are supported. Any 3G3RV-P10ST data area can be accessed from the 

DeviceNet master.

• The communications speed can be set to 500 kbps (total network length 100 m max.), 250 kbps (total network 

length 250 m max.), or 125 kbps (total network length 500 m max.).
