tination unit can be changed to mode 3 automatically by the instruction. Refer to
Section 5 Instruction Set for details on IODP(189).
Mode 4 is not being used currently. In mode 4, the display will show only the deci-
mal point indicating it is in mode 4.
A total of four Peripheral Devices can be connected to a CV-series PC, as shown
in the following table. Only one Peripheral Device can be connected to the CPU
or an I/O Interface Unit.
If a Peripheral Device is connected to the CPU or an I/O Interface Unit, 3 more
Peripheral Devices can be connected to SYSMAC BUS/2 Remote I/O Slave
Units. If no Peripheral Devices are connected to the CPU or I/O Interface Unit, 4
Peripheral Devices can be connected to SYSMAC BUS/2 Remote I/O Slave
Units. Up to 2 Peripheral Devices can be connected to Remote I/O Slaves under
a single Remote I/O Master Unit.

Peripheral Devices can be connected even when the PC is ON. Insert the cable
connector until it locks. Using pins 1 and 2 on the CPU DIP switch, set the baud
rate to 50,000 bps for the Graphic Programming Console or Programming Con-
sole or to 9,600 bps for a computer running the CV Support Software.
If the ERROR indicator lights when the PC is turned ON, find the source of the
error by displaying error messages at the terminal. For a memory error, perform
the memory clear or program transfer operation online from the CVSS/SSS and
then clear the error. If a memory error cannot be cleared, there might be a hard-
ware problem in the CPU.
Note 1. I/O tables cannot be created or edited and broadcast testing is not possible
for SYSMAC LINK Systems if the Peripheral Device is connected to a Slave
in a SYSMAC BUS/2 Remote I/O System.
2. Refer to Appendix A Standard Models in the CV-series PC Installation
Guide for a list of available Peripheral Devices.
The following is an overview of the PC configuration. Refer to the CV-series PC
Installation Guide for details.
The basic PC configuration consists of three types of Rack: a CPU Rack, an Ex-
pansion CPU Rack, and one or more Expansion I/O Racks. The Expansion CPU
Rack and Expansion I/O Racks are not a required part of the basic system.
An Expansion CPU Rack is used when the CPU Rack cannot accommodate the
required number of CPU Bus Units (SYSMAC BUS/2 Remote I/O Master Units,
BASIC Units, SYSMAC NET Link Units, and SYSMAC LINK Units). Expansion
I/O Racks are used to increase the number of I/O points, but do not support CPU
Bus Units. An illustration of these Racks is provided in 3-3-1 I/O Area .
An Expansion CPU Rack cannot be connected to a CVM1-BC103/053 Back-
plane.
A fourth type of Rack, called a Slave Rack, can be used when the PC is provided
with a SYSMAC BUS or SYSMAC BUS/2 Remote I/O System.
A CPU Rack consists of four components: (1) The CPU Backplane, to which the
CPU, the Power Supply, and other Units are mounted. (2) The CPU, which
