CPU MODULE PROCESSING TIME
(Example)
When the number of auto refresh points for the analog-digital conveter module
(Q64AD) is 4 points (when the module is mounted on the Q01CPU main base
unit)
0.249(ms) = 0.085 + 0.041 4
(7) Service processing time
Service processing indicates the processing for communication with GX Developer
and external device.
(a) Basic model QCPU
• Monitor by GX Developer
This indicates the processing time taken to execute monitor by GX
Developer.
* 1 : Time taken to read an 8k-step program from the program memory.
* 2 : Time taken when 32 points have been set in registration monitor.
* 3 : Time taken when a 100-step ladder is added.
* 4 : Time taken when access is made via the MELSECNET/H, Ethernet, CC-Link or serial
communication module.
• Communication with serial communication module or Ethernet interface
module
This indicates the time taken to communicate with the serial communication
module or Ethernet module.
Refer to the following manual for the time taken for communication with each
module.
