Summary:
We performed testing between the subject device and our MVI56-MCM product. Our testing generated the following results:

We were able to successfully communicate with the device. (see below for configuration parameters used during the testing)
The product supported Modbus functions 1,2,3,4,15 & 16

The purpose of our testing is to assure a level of compatibility in the communications between the two products. Through this testing, we attempt to identify problem areas that may arise when implementing the interface in the field.

Configuration:
The product testing was performed with the following settings used:

Baud: 115K
Parity: None
Stop: 1
Mode: RTU Master Mode
Physical Connection : RS-232

The Module Configuration used in our testing was as follows:

Command List:
The following command list shows some of the commands which were used to test the communications:

Parameter x = 0 x = 1 x = 2 x = 3 x = 4 x = 5

MCM1.P1Cmd[x].Enable 1 1 1 1 1 1

MCM1.P1Cmd[x].IntAddress 9600 0 601 602 1 606

MCM1.P1Cmd[x].PollInt 0 0 0 0 0 0

MCM1.P1Cmd[x].Count 4 4 4 4 2 2

MCM1.P1Cmd[x].Swap 0 0 0 0 0 0

MCM1.P1Cmd[x].Device 1 1 1 1 1 1

MCM1.P1Cmd[x].Func 1 15 2 4 16 3

MCM1.P1Cmd[x].DevAddress 0 0 0 0 1 0

Our test command list perfoms the following functions.

CMD 0 (Column x=0) Read coil status.
CMD 1 (Column x=1) Force Multiple Coils.
CMD 2 (Column x=2) Read input status.
CMD 3 (Column x=3) Read input registers.
CMD 4 (Column x=4) Preset multiple registers.
CMD 5 (Column x=5) Read holding registers.

Cable Connection:

The physical connection which was used during testing was as follows:

MVI56-MCM Module		ICL-4300
2 TXD	--------------------------------	3
3 RXD	--------------------------------	2
5 GND	--------------------------------	5
