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.
The term local PLC is used here to identify the
The term SRTP Serveris used here to identify the Host server.

(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
