Send Information Report (2010)

The Send Information Report COMMREQ requests that a particular block of memory
within the PLC CPU reference tables be transferred periodically from an Ethernet
Interface (SRTP Client) to a Host Application SRTP Server. The Command Block
specifies the repetition period, the number of transfers to the server to perform, and the
timeout allowed in waiting for each transfer to complete. The first send is performed
immediately, regardless of the period specified.

Example Command Block

Establish a channel (channel 7) to a remote Host application server at IP address 3.0.0.1.
Return the COMM_REQ Status word to %R10. Send local PLC registers %R50–%R57 to
remote host. Repeat the send 10 times once every 7 seconds with a timeout of 500 ms
for each read.

* Word 4 (CRS word address) is the only zero–based address in the Command Block.
Only this address requires subtracting 1 from the intended address.

(Word 7) Channel Command Number:

Word 7 requests that a Send Information Report

channel be set up. If the command is processed successfully, it will result in attempting
the specified number of transfers from the client to the server.

(Word 8) Channel Number:

Word 8 specifies the channel to be used for the send. This

value must be in the range of 1 to 16. If the channel is out of range, a command error
