Mixed Module, 24 V DC Positive Logic Input 20 Points / Output 12 Point /
(4) High-speed Counter, PWM, or Pulse Train Configurable Points
Output Defaults
If the CPU or NIU stops communicating with the High Speed Counter module,
so that the module no longer receives fresh output data, counter operation
continues normally.
Normal
(default setting) The inputs continue to be processed by the module.
The outputs continue to operate as if the CPU or NIU were present, changing
state to reflect the counter Accumulators.
Preset outputs can also be configured to operate in the following modes if the
CPU stops providing output data:
Force Off
All Preset outputs are turned off and remain off until the CPU
returns to normal operation.
Hold Last
The Preset outputs retain current levels and do not reflect the
counter Accumulators.
