Appendix 4 Performance List Of Simple Plc Communication Function - Mitsubishi L02CPU User Manual

Appendix 4
This section shows the performance of the execution interval (simple PLC communication function). The execution
interval varies depending on the number of settings, the number of communication points, the scan time of the CPU
module. The interval is also affected by the execution conditions of other functions or Ethernet communication
condition.
(1) Condition 1
• Communication Setting: "Fixed Interval"
• Destination device: "MELSEC-Q/L (Built-in Ethernet Function)" = L26CPU-BT
• Sequence scan time (host station): 1ms (the period before the execution of simple PLC communication
function)
• Sequence scan time (destination device): 1ms (The destination device means both the transmission source
and transmission destination for data transfer.)
• Device data: Bit device = M, Word device = D
• Number of settings: The number of destination devices (Double the number for data transfer.)
• The retry of communication is not performed.
