 It is required to reset controller's POWER (Power OFF -> Power ON) after changing
communication speed (bps) via Power/Comm. connection terminal.
 One module communication is allowed for PC loader port. Communication speed is fixed to
9600 bps.
 Make sure that each module has its own communication address. If there are overlapping
addresses, parameters for overlapping module cannot be monitored and it may affect the
whole communication speed.
6.5.3 Communications parity bit
Parity bit is a data communication method that adds an additional bit to each character in
transmitted data as an indicator used to verify data loss and corruption. This parameter is used
to enable or disable the parity bit option.
SV (setting value)
Description
NONE Disables parity bit.
EVEN Sets the total bits with signal value of 1 as even numbers.
ODD Sets the total bits with signal value of 1 as odd numbers.
