Introduction
The Link PLC interface is intended to allow communications between Link equipment and generic
external devices (primarily PLCs, but other devices could be used - the term PLC will be used in this
manual to refer to both) . Features include:
Up to 4 user defined screens can be configured.
Each screen can be given a title and a softkey name for navigation.
Each screen can have up to 16 user defined parameters.
Each screen can have up to 5 user defined “action” softkeys.
Each screen can have up to 4 user labeled screen status messages. These messages are 40
characters long and can be color coded. Up to 256 different status messages can be configured
and are shared across all screens.
Each parameter is named by the user and can consist of a numeric value, a status message, or both.
Each numeric value parameter has a number of digits, decimal place, maximum value, minimum
value, and unit of measure associated with it.
Each parameter status message is 15 characters long and can be color coded. Up to 64 different
parameter status messages can be configured and are shared across all parameters.
All user parameters are stored with the OmniLink job. When the system is powered up or a new job
is recalled, the user parameters are automatically sent to the PLC. In addition, the PLC can request
the parameter values at any time.
The OmniLink job number can be configured to be sent automatically to the PLC when the system is
powered up and when a new job is recalled.
Many parameters from the press control, such as mode, status, crank angle, and other values can be
requested by the PLC.
The PLC can tell the OmniLink to recall a job number.
