Inter Scan Delay (ms)
The Inter Scan Delay defines the scan rate, in terms of a minimum delay between accesses in milliseconds.
For example, if the delay is 100, the point group will not be scanned until 100 milliseconds have elapsed since
the last time it was scanned.
Register Type
For Bool Point Groups
only, this entry selects the source of the data. Select “Input” for MODBUS Discrete
Inputs data, or “Coil” for MODBUS Coils data. A master port cannot have an output point group of type “Input”.
Integer Status
The Point Group Integer Status input is an Int Variable that supplies operating information for the Point Group.
Its meaning is as follows:
0
Normal
1
Exception status from MODBUS response message
Bool Send Request
This variable allows the user to control when values are requested/transmitted while in MODUS TCP Master
Mode only. This variable is ignored in all other MODBUS configurations.
If this variable is enabled (Type set to BOOL), the values of the point group will be transferred ONLY when the
value of this variable transitions from FALSE to TRUE.
When this variable is enabled, regular polling via the Inter Scan Delay will be disabled.
Channel
Up to 16 Bool input or output points can be configured for each Point Group. Initially, all I/O points are enabled
(Bool). To access a Bool input or output point, it must be enabled (Bool). Disabled points will not be scanned.
The first point in a group should always be enabled; disabled points within a group are allowed.
I/O Tag
Each Bool input or output channel is accessed by a Bool Variable object. NetArrays assigns a Tag to each
channel when the channel is enabled. Reconfigure the I/O Tag as required to match the Module Form Bool
Variable object that is used to access the channel.
