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(8) to ON. Each bit at addresses 00751 to 007757(8) corresponds to a 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.
