5.
Cir-No (line 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.1 MPE720 Module Configuration Definition Window
The following table shows the scope of circuit numbers.
6.
Ch-No (communication buffer channel number)
Specify the channel of the communication buffer.
It can be any channel in the scope. However, when starting up 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 shows the scope of channel numbers.
When the communication device is Ethernet (218IFA), because the communication buffer common to the trans-
mission and reception has four channels, four transmissions (or receptions) are available at the same time by
using channels 1 to 4.
Note: 1. As many MSG-SND (or MSG-RCV) functions as lines used at the same time are required.
2. For information on communication buffer channels, refer to G.3 Communication Buffer Channel on
page A-102.
