Register monitor data(command: 06, 07)
Registers bit devices (X, Y, M, etc.) to be monitored in 1-point units. (Command: 06)
Registers bit devices (X, Y, M, etc.) to be monitored in 16-point units. (Command: 07)
Registers word devices (D, T, C, etc.) to be monitored in 1-point units. (Command: 07)
■Request data
• Number of device points: Specify the number of devices to be registered as a monitoring data. (Page 402 Number of
device points)
• Fixed value: '0'.
• Device number: Specify the device number to be registered as a monitor data. (Page 397 Device codes and device
numbers)
When specifying bit devices at monitor data registration in word unit, set the device numbers in multiples of 16
( 0, 16, ... in decimal notation).
■Response data
There is no response data for this command.
■Communication example
Register devices as a monitoring data in the CPU module with E71 mounted under the following conditions.
• Number of device points: 3 points
• Device number: Y46, M12, B2C
