Output message literal fields

Output message fields can be defined to contain literal data you specified during definition of the MOD. MFS includes the specified literal in the output message before sending the message to the device.

You can define your own literal field, select a literal from a number of literals provided by MFS, or both. The MFS-provided literals are called system literals, and include:

• Various date formats
• The time stamp
• The output message sequence number
• The logical terminal name
• The number of the logical page
• The queue number of the message waiting
