Max. transmission delay
Link Service processing (source node)
Assume that the sum of the instruction execution time and I/O refresh time for
the PLCs at nodes #1 and #7 is 1 ms. The equation for minimum data link I/O
response time is as follows:
Noise may increase I/O delays.
The two charts which follow indicate the sequence of processing which will
enable users to calculate the maximum delay time to be expected between
the time SEND(192) or RECV(193) is executed and the time the data is stored
in the destination or source node’s memory area, ready for use by other
instructions in the program.
The following diagram indicates the data flow which will yield the maximum
delay time from the time SEND(192)/SEND(90) is executed by the user pro-
gram to the time the Controller Link Unit stores the data in the destination
Unit’s memory.
