Conditions

for usage

Settings

PLC Setup: Shared Settings for Communications Instructions in FBs

• DeviceNet Response Timeout Time (default: 2 s) 10 s recommended

• Number of retries (default: 0)

Shared Resources

• Communications ports (internal logical ports)

Other

• Communications must be within one network and cannot cross to another network.

Function

description

When the start trigger turns ON, one element, a present value or set value, is written to the specified Variable

Type and Write Address in the Controller on the DeviceNet specified by the Master unit No., Slave node

address, and Controller unit No.

Refer to the manual for the Controller being used for details on variable types and read addresses. (See

Related manuals .)

precautions

• The FB is processed over multiple cycles. The BUSY output variable can be used to check whether the

FB is being processed.

• OK or NG will be turned ON for one cycle only after processing is completed. Use these flags to detect

the end of FB processing.

EN input

condition

Connect EN to an OR between an upwardly differentiated condition for the start trigger and the BUSY output

from the FB.

Restrictions

Input

variables

• Always use an upwardly differentiated condition for EN.

• The applicable ranges for input variables depend on the Controller being used. Set values that are

appropriate for the Controller.

Output

variables

• This FB requires multiple cycles to process. Always connect an OR including the BUSY output variable

to the EN input variable to ensure that the FB is processed to completion (see Symbol ).

• Do not turn the BUSY output variable ON or OFF outside the FB.
