The minimum and maximum I/O response times are shown here, using as an
example the following instructions executed at the master and the slave. In this
example, communications proceed from the master to the slave.
Output (LR)
The following conditions are taken as examples for calculating the I/O response
times.
Input ON delay:
Master cycle time:
Slave cycle time:
Output ON delay:
Number of LR words: 64 words
1. The C200HX/HG/HE receives an input signal just prior to the input refresh
phase of the cycle.
2. The master to slave transmission begins immediately.
3. The slave executes communications servicing immediately after comple-
tion of communications.
