Silent interval multiplier (No.45 SIVM)
This parameter is not used for this controller. It is applied to controllers of RS485 serial communication
type.
If specified, this parameter defines the multiplier to be applied to the silent interval time for delimiter
judgment in the RTU mode.
The default setting is the communication time corresponding to 3.5 characters in accordance with the
Modbus specification.
This setting need not be changed for normal operations performed with a PC or teaching pendant.
If the scan time of the PLC is not optimal and the character transmission interval exceeds the silent
interval, the silent interval time can be extended using parameter No. 45.
The minimum setting unit is “1 [time],” while the input range is “0 to 10.” If “0” is set, no multiplier is applied.
