5.
Cir-No (circuit number)
Specify a circuit number for the communication device.
Specify it in accordance with the circuit number displayed in the MPE720 Module Configuration Definition
Window.
Fig. G.9 MPE720 Module Configuration Definition Window
The following table indicates the range of valid circuit numbers.
6.
Ch-No (communication buffer channel number)
Specify the channel number of a communication buffer.
It can be any channel number in the range. However, when starting multiple functions at the same time, set a
unique channel for each function. (If you do not start up multiple functions at the same time, the channel numbers
can duplicate each other.)
The following table indicates the range of valid channel numbers.
When the communication device is Ethernet (218IFA), because the communication buffer common to the trans-
mission and reception have four channels, four receptions (or transmissions) are available at the same time by
using channel numbers 1 to 4.
Note: 1. As many MSG-RCV (or MSG-SND) functions as lines used at the same time are required.
2. For information on communication buffer channel, refer to G.3 Communication Buffer Channel.
