Set connection status of slave station [bit pattern, byte]
• In the initial settings of the data link function, the JW-20CM will not display errors (on the LEDs on
the panel, or in the system memory) even if it detects a communication error in a slave station. In
order to display the error when a slave station communication error is detected, set bit 0(E) at
parameter address 007750
slave station. Turn ON the respective bit if required. (See page 13·15.)
With the setting above, the JW-20CM will display errors when a slave station whose corresponding
bit is ON produces a communication error.
Ex.: Setting the bits to output errors for slave
stations 01 and 02 using the JW-13PG.

· If a bit corresponding to a slave station is turned OFF, the module will not display an error code
