Handling Precautions
Section 10-7
maximum number of nodes in the network is 31. For details, refer to Duplex
Specifications on page 169.
10-7-2 Replacing the Unit
Observe the following precautions when replacing the Unit.
• Always turn OFF the power before replacing the Unit.
• Check that the new Unit is not faulty.
• If you suspect that a poor connection is the cause of a malfunction, clean
the connectors using a clean, soft cloth and industrial-grade alcohol.
Remove any lint or threads left from the cloth, and remount the Unit.
• When returning a faulty Unit for repairs, always attach a detailed fault
report to the Unit and return to you nearest OMRON outlet as listed at the
back of this manual.
Note In order to prevent faulty operation be sure to turn OFF the power to all nodes
before replacing the Unit. In an Optical Ring system, it is possible to replace a
Unit while the system is operating as long as specific conditions are met.
Refer to Replacing a Unit while the System is Operating on page 253 for
details. (In a CS1D System, online replacement is possible.)
When replacing the Unit, do not reconnect that node to the Network before
carrying out the procedures listed below. In particular, a node with a small
address will become the polling node and communicate the initial network
parameter status to other nodes, so there is the chance that network parame-
ters in the entire Network will be damaged.
10-7-3 Setting the Unit after Replacement
After replacing a Controller Link Unit, reset the hardware switches, software
switches, and data link tables, and wire it in the same manner as the previous
Unit. This section describes settings that require particular care. Refer to the
Unit replacement methods later in this section for details on replacing the Unit.
!Caution
After replacing the CPU Unit, transfer important data, such as DM and HR
Area contents, to the new CPU Unit before restarting operation. Depending
on the program, accidents can occur as a result of incorrect DM or HR Area
contents.
CVM1 and CV-series Controller Link Units store data such as data link tables,
network parameters, and routing tables in the CPU Unit. When replacing the
CPU Unit, reset these settings using the Controller Link Support Software.
Setting the Transmission Format
There are three kinds of CS-series Optical Controller Link Units: the CS1W-
CLK11 Optical Bus Controller Link Unit, the CS1W-CLK12/12-V1 Optical Ring
Controller Link Unit which uses H-PCF cable, and the CS1W-CLK52/52-V1
Optical Ring Controller Link Unit which uses GI cable.
The following transmission format setting must be made in advance when
using a CS1W-CLK12/12-V1 Optical Ring Controller Link Unit as a substitute
for a CS1W-CLK11 Optical Bus Controller Link Unit. (The CLK52/52-V1 Opti-
cal Ring Controller Link Units (GI cable) cannot be combined with CLK11/11-
V1 Optical Bus Controller Link Units or CLK12/12-V1 Optical Ring Controller
Link Units (H-PCF cable).)
The control bits for CS-series Controller Link Units are in (100
×
unit number).
