Parameter Areas
The accuracy of the clock pulses is different for Duplex CPU Systems than for
Single CPU Systems or CS1-H CPU Units.
Accuracy in Normal Operation
The following table shows the clock pulse accuracy in normal operation.
Accuracy when Switching from Duplex to Simplex Operation
The accuracy of the clock pulses may be longer in the first cycle after switch-
ing from duplex to simplex operation. The following table shows the clock
pulse accuracy in the first cycle after switching.
Unlike the data areas in I/O memory which can be used in instruction oper-
ands, the Parameter Area can be accessed only from a Programming Device.
The Parameter Area is made up of the following parts.
The user can customize the basic specifications of the CPU Unit with the set-
tings in the PLC Setup. The PLC Setup contains settings such as the serial
port communications settings and minimum cycle time setting.
Refer to SECTION 6 PLC Setup for details on the PLC Setup settings and
refer to the Programming Device’s Operation Manual for details on changing
these settings.
The Registered I/O Tables are tables in the CPU Unit that contain the informa-
tion on the model and slot location of all of the Units mounted to the CPU
Rack and Expansion I/O Racks. The I/O Tables are written to the CPU Unit
with a Programming Device operation.
The CPU Unit allocates I/O memory to actual I/O points (on Basic I/O Units or
Remote I/O Units) and CPU Bus Units based on the information in the Regis-
