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.
Example1 Command Block–Basic Example
Establish a channel (Channel 7) to a remote Host application server at IP address 10.0.0.1. Return
the COMMREQ 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 transfer.

* Word 4 (CRS word address) is the only zero-based address in the Command Block.
Only this value 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 1–32 for Series 90-70 PLCs and 1–16 for Series 90-30 PLCs. If the
channel number is out of range, a command error indication will be placed in the COMMREQ
Status word. If the channel number is the same as a channel already in use, the channel will be
re-tasked to perform this new command.
(Word 9) Number of Send Repetitions:
Word 9 specifies the number of transfers to be
performed before automatically completing the communications request and closing the channel.
The term local PLC is
used here to identify the
client PLC—the PLC
that initiates the
communications
request.
The term SRTP Server
is used here to identify
the Host server.
