Communication Cycle Time
Displays the internal device addresses to store the specified device/PLC communication cycle time (unit: ms).
The Communication Cycle Time is the time from when the display unit requests data from the device/PLC, until the display unit receives the data. The communication cycle times for each device/PLC when communicating with multiple devices/PLCs are stored using the address scheme shown here.
The communication cycle time for the [System Area Device] (defined in the [System Settings], [Display Unit], [System Area] tab) is stored in internal device address LS2037 in Bin format. The unit is 10 milliseconds.
If LS area is 32 bit, the value is stored in the lower 16 bits.
