(6) Communication monitor time (ISD, EPR)
Initial value of ISD, EPR (when set to 0)
- The initial values of ISD and EPR are determined by the number of slave stations and the
settings on switch SW8.
- For details about switch SW8, ISD, EPR, see pages 8-10 and 8-11.
(7) Output status of the slave station when the control section stops operation (master mode)
When the JW-32CUM1 is used in the master mode, this system memory location is used to select the
data sent to the slave modules if a JW-32CUM1 (control section) stops operation (enters the program
mode). - See page 8-50.
* For details about slave station operation when a slave station receives idle data, see the instruc-
tion manual for each slave station.
The areas shown in gray in the figure below can be set to "send/clear idle data" when the control
sectionº stops operation.
