B2.2 Types of Registers
This module is provided with input/output relays for configuring module operation and
reading operation status. Registers for configuration include basic setup elements, as well
as supplementary setup elements for supporting various modes of operation. Set these
registers appropriately to suit the intended usage. In addition to registers for reading the
status of individual channels, other registers are provided to store process data for all
channels, arranged sequentially within a data area. Table B2.2 lists the categories of I/O
data registers provided, along with a short description for each category. Table B2.3 and
subsequent tables lists the I/O data registers by category.

Common Common process data These are representative process-related data for all channels.
It consolidates, in one data area, process-related data that are most commonly
monitored for all channels, such as process value, operating status and error
status.
B2.2.1
Setup control parameters Use these parameters to enable various settings, required when monitoring
parameters or input parameters are updated.
For details on the procedure, see Section B2.3, “How to Enable Settings.”
B2.2.2
B2.3
Function control
parameters
Use these parameters to configure the operation of module functions on a
module-wide basis.
B2.2.3
Monitoring parameters Use these parameters to set up the basic operation of the module, such as
Input Sampling Period and Monitoring mode, on a module-wide basis

Process data These are process-related data for each channel.
They include input process value, operating status, error status, etc., which
cane be used for monitoring the operation of the module.
B2.2.5
Operation control
parameters Use these parameters to control the operation of individual channels, such as
whether to perform reference junction compensation.

B2.2.6
Input
parameters
Input type
settings
Use these parameters to select input type for individual channels.
These parameters are the most basic setup elements for a channel.
B2.2.7
Input range
settings
Use these parameters to set up the input of individual channels, as required,
such as changing the input range, or selecting an appropriate burnout
operation.
B3.2
PV range
settings
These parameters are only valid in Two-input Changeover mode, and are
used for defining the PV range in Two-input Changeover control.
By default, the PV range follows the input range of the even channel.
Operation
parameters Two-input
change-over
functions
settings
Use these parameters to perform setup when using Two-input Changeover
mode.
They can be used for setting the changeover mode and changeover
temperature.
B2.2.8
Input functions
settings
Use these parameters to configure processing of input values of individual
channels, as required.
They can be used for setting input correction, square root extraction and input
filtering of the input, as required.
Alarm function
settings
Use these parameters to set up the operation of the alarm functions for
individual channel as required. They can be used to set the alarm type,
hysteresis, ON delay timer, as required.
SP parameter Use these parameters to set alarm preset values of individual channels.
Up to 4 sets of parameters can be set.
Monitoring parameters and input parameters must be enabled before any written content
can take effect. For details on how to enable such parameters, see Section B2.3, “How to
Enable Settings.”
