CPM2C-S Features and Functions Section 1-1
One-to-one PC Link A CPM2C-S can be linked directly to another CPM2C-S, CQM1, CPM1,
CPM1A, CPM2A, CPM2C, SRM1(-V2), C200HS, or C200HX/HG/HE PC. The
1:1 PC Link allows automatic data link connections. The PC must be con-
nected to the communications port as an RS-232C port (not as a peripheral
port).
1-1-2 Overview of CPM2C-S Functions
Main function Variations/Details
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-dis-
tance 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 (CPM2C
→
Master; read-only)
TC 000 to TC 255
•
Explicit message communications are supported. Any CPM2C-S 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.).
