Data Specified In The Command; Specification Of The Number Of Devices; Specification Of The Number Of Devices For Bit Access - Mitsubishi Electric A800-E Instruction Manual

Data specified in the command
• Device code
A one byte numerical value is sent.
• Device No. (first device No.) specification
The device No. is specified for reading/writing data.
When consecutive devices are specified, the first device No. is specified. The device No. is specified in decimal or
hexadecimal depending on the device type.
A three byte numerical value is sent from the lower byte to the upper byte. If the device No. is a decimal value, convert it to
a hexadecimal value.
(Example) Device No. of Internal relay M63 / Input X20
Internal relay M63 has a decimal device No. Convert the decimal value to a hexadecimal value H00003F. The value is sent
in the order 3F, 00, and 00. The device No. of Input X20 is regarded as H000020 and sent in the order 20, 00, and 00.

• Specification of the number of devices

The number of devices is specified for reading/writing data.
A two byte numerical value is sent from the lower byte to the upper byte.
(Example) Number of devices: 5 / 20

• Specification of the number of devices for bit access

The number of devices is specified for reading/writing data in bit units. The number is used in the Write random command
(refer to page 37).
(Example) Number of devices: 5 / 20
