(6) Examples of response delay time in the synchronous communication mode
An example is described in (a) to (d) regarding the operation of the coincidence output function in the following
condition.
• Master/local module is the QD77GF16
• Block data assurance per station is set
Operation of the coincidence output function
Ex.
CH Count enable command
CH
(Coincidence output 1)
Counter value smaller
(Coincidence output 1)
Coincidence output 1
(Coincidence output 1)
Counter value greater
(Coincidence output 1)
(a) Processing time (Normal value): Master station (RY)  Remote device station (RY)
The following shows the processing time required until the high-speed counter module starts pulse input after
CH Count enable command (RY24, RY3C) is turned on.
(SM  n2) + (CT  1) + Processing time of the high-speed counter module (T
• SM: Scan time of the program in the master station
• CT: Synchronization cycle
• n2: The value provided by rounding up the value after the decimal point of (CT  SM)
(b) Processing time (Normal value): Master station (RWr)  Remote device station
(RWr)
The following shows the processing time required until a count value is read by the master station after the
count value is counted by the high-speed counter module.
(SM  1) + (CT  n1) + Processing time of the high-speed counter module (T
• SM: Scan time of the program in the master station
• CT: Synchronization cycle
