Configuring the Slave Devices
Example
Removing I/O Modules
Watchdog Settings
4. Also in this window are the maximum values, which can be set, and the to-
tals of I/O data that actually have been set. If - while selecting I/O modules
- one of the maximum values is exceeded, a warning message will be dis-
played.
For the CJ1W-PRT21, the first four I/O modules have been selected, see fig-
ure below.
To remove I/O modules from the Configured Modules list, perform one of the
following procedures.
• Select the I/O module that needs to be removed from the Configured
Modules list, and double-click it with the left mouse button. If more than
one module must be added, repeat this step for the other modules.
• Select the I/O module that needs to be removed from the Configured
Modules list, and press either the Remove button. This method allows
selection of more than one module, by pressing either the Shift or the Ctrl
key on the keyboard, while selecting the modules.
Apart from the I/O module selection, the Configuration tab also contains the
settings for two other parameters.
1. Enable Watchdog Control
This parameter will enable/disable the monitoring of the Master-Slave
communication in the slave device. If enabled, the slave will stop I/O data
exchange with the Master, if the Master has not send any request message
to the slave, within the configured Watchdog time. Furthermore, the slave
will
• switch its outputs to a known state.
• signal its change of state in a diagnostics message, the next time the
Master addresses the slave.
