Send message to one or more linked phases and wait values

Configure the PXRQ instruction in

Logix Designer

to send a message to one or more linked phases and wait for a response:

External Request	Data Value Array Element	Value
Send Message to Linked Phase and Wait	DINT[0]	message ID
	DINT[1]	number of phases to receive message
	DINT[2]	message value

The data value array can contain up to 97 message values.

The receiving partners must issue a request before the data is sent. The sending partner may send the data at anytime. The sending phase waits for confirmation of the responses from the total number of receivers before continuing. The data is cached in the

FactoryTalk Batch

Server until the receiving partner(s) makes a request to receive the data.
