PAC Serial Control

PICED Logic Programmer's Guide says:

For use with the Pascal Automation Controller, there are the following limitations :
SerialPortIndex is the User Port number (1 or 2)

Can i have two PAC's and control four devices on one network?
If so, how?

Thanks

Each 5500PACA has 2 serial ports that you can address independently. When writing logic to control the device, you address the serial ports using the SerialPortIndex as either 1 or 2.

Each 5500PACA requires it's own logic to be written and downloaded. When addressing the serial ports, the SerialPortIndex is with reference to that unit only. You cannot address serial ports on one unit directly from the logic code in another unit.

From memory, you can have up to 30 5500PACA's on a single C-Bus network, so you could, in theory control up to 60 devices connected to RS-232.
