Related Parameters
Remarks
A unique name up to identify the block in the system. The module name should reflect the type of module being used and its location. This will make tracking easier in the future when you add more modules to your system. For example, the module name PI_IOM_01 might stand for Pulse Input - Input Output Module - Primary chassis. This name appears on all related system displays and any generated reports.
IOMTYPE

All IOM function blocks
Description
This non-configurable parameter is a description of the respective IO module type.
Data Type
String

Default
Defined appropriately on each I/O module type. See Note below.
Config Load
Not configurable, but loaded to SR
Access Lock
View Only
Residence

IOMNUM
Specific to Block(s)
All IOP Blocks
Description
I/O Module Number. Defines the logical address of the associated I/O Processor (IOP) on the given I/O Link.
Data Type

IOLIM
Related Parameters
Remarks
This parameter value must be unique on a specific I/O Link, and its range must be between 1 and 40.
If IOMNUM=0 and the IOP block is assigned to an I/O Link block, Control Builder automatically defaults the IOMNUM to the next available value on the I/O Link.
IOMSTATE
Specific to Block(s)
All IOP Blocks
Description
I/O Module Execution State. Defines the current execution state of the associated I/O Processor (IOP).
Data Type
Enum

IOP
Related Parameters
Remarks
The IOP must be in its RUN state for I/O data to be used by a loaded control strategy. We recommend that you activate the IOP block before activating its associated I/O Channel (IOC) blocks.
