6. Parameter Settings

z Silent interval multiplication factor (No.45 SIVM)

It is applied to controllers of RS485 serial communication type.

If specified, this parameter defines the multiplication factor 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 multiplication factor is

applied.
