1, 2, 3...
Each operation mode set command consists of a command code and parame-
ter. The following command codes are used for the operation mode A and opera-
tion mode B set commands.
• Operation Mode A: C000
• Operation Mode B: C200
Refer to pages 208 to 211 for the details of the parameters used for the Unit.
In this example, the following operation modes are selected for the Unit.
• Data Input:
• Timing Hold Mode:
• Input Type:
• Monitor Output:
• Input Sampling Speed:
• No. of Averaging Process Times: 1
• Zero Shift Value Storage Area: RAM
In this example, the initial parameters have been set. Described below is the
method of changing the data input and input type using the operation mode A set
command.
1. The input word reads 1254, which is the present scaled conversion data,
and the output word reads 0000.
2. Set the command code C1000 to the output word to in order to set the opera-
tion mode A. To input the letter C with the Programming Console, press the
Shift and 2 Keys.
The input word will be set to the response C000.
