Slave Function

It takes approximately four seconds from the time that the Devicenet Unit is turned ON or restarted as a slave until remote I/O communications with the master begin.

8-2 Message Communications

8-2-1 Message Communications Time

The message communications time is the time required from the time a Mas- ter Unit starts to send a message over the Network to another node until the Master Unit completes sending the message (data for SEND(192)/ RECV(193) and FINS commands for CMND(194)/IOWR).

The following equation can be used to compute the approximate message communications time.

Message communications time =

Communications cycle time x ((No. of message bytes + 15) ⎟ 6 + 1) No. of message bytes: No. of data bytes following the FINS command code

The communications cycle time depends on whether or not remote I/O com- munications are being used.

Message Communications Only (No Remote I/O Communications)

The following equation can be used to compute the message communications time when remote I/O communications are not being used.

Communications cycle time =

2 (see note) + 0.11 ⋅ TB + 0.6 [ms]

TB : The baud rate factor

(500 kbps: TB = 2; 250 kbps: TB = 4; 125 kbps: TB = 8)

Note The communications cycle time will be 2 ms even if remote I/O communica- tions are not being used.

Remote I/O and Message Communications

Performing message communications in addition to remote I/O communica- tions will increase the message communications time.

Communications cycle time=

Communications cycle time for remote I/O communications only + 0.11 ⋅ TB + 0.6 [ms]

TB : The baud rate factor

(500 kbps: TB = 2; 250 kbps: TB = 4; 125 kbps: TB = 8) (Varies depending on the baud rate.)
