Setting up direct driver communications

2–13
Example: An event for switching drivers
In the Events editor, use the following:
Action DriverToggle 1
Expression comm_err(tag1)
where tag1 is a tag that is configured with a node on channel 1.
When the expression evaluates to true, the action is triggered.
Switching drivers manually
To switch drivers manually, operators must have a way to issue a driver
command. Possible methods are:
creating a button and specifying one of the driver commands as
the press action. When the operator activates the button, the driver
on the specified channel is switched.
displaying a command line. When the operator enters a driver
command on the command line, the driver on the specified
channel is switched.
Creating a node
A node allows you to assign a logical name and an address to each
programmable controller that RSView32 will communicate with. Each
programmable controller is then referred to throughout RSView32 by
this name. The node name carries all its configuration information, so
attributes such as type of programmable controller, station number,
and network type need not be repeated.
