11-3 Setting contents of master station parameters

[1] Setting contents

When the JW-21MN is used as a master station, set the following items for parameters.

When the JW-21MN is used as a slave station, setting contents of the parameter address 004004 to 004377(8) and 004404 to 004777(8) may vary with the data link setting condition as a slave station (standard function/save memory function).

For details of the parameter memory, see pages 16-8 to 16-12.
