1, 2, 3… 1. Allocate a slot to be a Sysmac-Bus Master unit. The Enter RM Number dialog is displayed.
2. Select a unit number from the Unit Number field, either 0 or 1.
3. Select the OK pushbutton to complete the operation or the Cancel pushbutton to abort the
operation.
The Sysmac-Bus Master unit provides two types of slave units that can be applied to the slave rack in the same
manner as a normal rack:
♦ C500H Remote Terminal (RT);
♦
C200H Remote Terminal (RT).
Any units on the slave racks or other Remote IO Units connected to the master are allocated IO words according to
the slot where the master is located.
For C1000H and C2000H PLCs, Word multipliers are required to set the base address of IO Terminals on each
SYSMAC-BUS Remote Master.
SIOU/Communications Units
SIOU/Communications Units can only be set up for CV-series PLCs and CS/CJ/CP series PLCs.
For CV-series PLCs SIOU/Communications Units the following Unit Setup and Software Switches setup can be
performed:
♦
Basic (Software Switches setup only);
♦ DeviceNet Master (Software Switches setup only);
♦
Controller Link;
♦
Ethernet;
♦ Host Link;
♦
ISA Board Unit (Software Switches setup only);
♦
ME-Net (Software Switches setup only);
♦
Mini-map (Software Switches setup only);
♦
M-Net (Software Switches setup only);
♦
Motion Controller (Software Switches setup only);
♦
PC (Software Switches setup only);
♦
Syslink;
♦
Sysmac-Bus Master;
♦
SysNet.
For CS/CJ series PLCs SIOU/Communications Units the following Unit Setup and Software Switches setup can
be performed:
♦
Controller Link Unit;
♦ Device Net and Open Network controllers;
♦
Ethernet Unit;
♦
Serial Communications Unit (Software Switches setup only).
Most of the settings for SIOU/Communications Units should have been set via the PLC setup component. Refer to
Chapter 4 - PLC Setup Component for further details.
Refer to Chapter 3 - Unit Setup and Software Switches for further information.
Caution: Setup to SIOUs that have already been registered should be applied carefully.
Verifying Correct Configuration
If a change is made to the IO configuration that affects a type of IO word or the number of words required by a unit,
for instance adding or removing units, an IO verification error occurs. Select
Verify from the Options menu to
ensure that an IO verification error has not occurred. If an error has occurred, use the procedures explained in
Chapter 3 - Creating an IO Table, Chapter 3 - Slot Allocation and Chapter 3 - Transfer an IO Table
to rectify any
error.
