MODULE INSTALLATION
The PMIO Scanner is a standard single slot ControlLogix module and fits directly into any ControlLogix
chassis. All required power for the module is derived from the ControlLogix backplane. On the front of the
module are 2 x 3-way communication connectors for the redundant I/O Link to the Honeywell IOP Rack(s).
LED
Description
Ok
The module LED will provide information regarding the system-level operation of the
module. If the LED is red, then the module is not operating correctly. For example, if the
module application firmware has been corrupted or there is a hardware fault the module will
have a red Module LED.
If the LED is green (flashing), then the module has booted and is running correctly without
any application configuration loaded.
If the LED is green (solid), then the module has booted and is running correctly with
application configuration loaded.
A / B
LED A represents Channel A of the I/O Link and LED B represents Channel B of the I/O Link.
Each time a valid packet is received on a specific channel the relevant LED will flash green.
When a corrupted packet is received the relevant LED will flash red.
I/O LINK
The pair of 3-way I/O Link connectors are used to connect to the TDC 3000 I/O. The details of the I/O Link
connector are shown below.
