Restrictions on controlling multiple Controllers

Controlling multiple Controllers has restrictions as described in the following sections.

Restrictions on Controller options

The following Controller options controlled by each Controller have restrictions.

• PC vision
• Fieldbus master

When one of the above three options is already connected to the active Controller, these options cannot be used for other (the second or later) Controllers.

Restrictions on simulator

Simulator window display
Epson RC+ 8.0 simulator window can be used from the .NET application. See below for details.
Windows

If the simulator window is opened for each Controller when multiple Controllers are connected, the cycle time may increase by 100 to 200 msec compared to not displaying the simulator windows.
Also, if the program is executed with the simulator windows open, the CPU utilization increases near 100 % and a huge load may be put on the PC.

It is recommended to use the system with the simulator windows closed, except when debugging the program.

Collision detection
To avoid collision with peripherals using the simulator, set 15 mm or more margins around the simulator object to avoid collision detection.
Collision detection in the simulator does not guarantee the accuracy. When applying to the actual system, make sure to set the margins and check operation adequately.
For details on each restriction, refer to Simulator Specifications and Restrictions in Epson RC+ User’s Guide.
