DC: Beginning Control Code Word

Specify the beginning word address of the area for storing the required control codes for message com- munications. The control codes shown in the following table are required by CompoBus/D Master Units. Preset the data in consecutive words.

14 to 8

 

7 to 0

 

 

 

 

C

Number of command data bytes: 0000 to 00A0 hex (0 to 160 bytes)

 

Set the amount of data from the beginning S word.

 

 

C+1

Number of response data bytes: 0001 to 00A0 hex (0 to 160 bytes)

 

Set the size of the data storage area from the beginning D word.

C+2

Network address: 0001 to 007F hex (1 to 127)

 

 

When using CMND(194) with the CV Series, a network address must be set for each

 

CompoBus/D Master Unit. The network address is edited using the routing table edit

 

function of a Peripheral Device (except for the Programming Console).

 

 

 

C+3

Command destination node address: 00 to

 

Command destination Unit address

 

3F hex (0 to 63)

 

 

Set Master Unit (FE) or Master Unit’s unit

Communications port no.: 0 to 7

 

Number of retries: 00 to 0F hex (0 to 15)

 

 

 

 

 

Set the number of times to resend for error

C+5

Response monitor time:

 

 

0000 hex

2 s

 

 

0001 to 028F hex 0.1 to 65.5 s (unit: 0.1 s)

 

Set at least 2 seconds for explicit messages.

 

Note Set “0” in word C+4 bit 15 to require a response or “1” to not require a response. Responses are required for explicit messages, so set “0.”

HMessage Timing

When executing CMND(194), an AND condition must be set that requires both the PC’s Network Com- munications Enabled Flag and the Master Unit’s Message Communications Enabled Flag to be ON.
