declaration in the server ladder program) to be used with access to remote %L memory. These words are required only for access to such memory RX3i and RSTi-EP TCP/IP Ethernet Communications User Manual Section 8 GFK-2224Y August 2019 Programming SRTP Channel Commands 157 8.3.4 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 a Third party Ethernet interface to a host application SRTP server. Currently PACS Ethernet devices do not support this server capability. 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. 8.3.4.1 Example Command Block 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 500ms for each transfer. Word Offset 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. If the channel number is out of range, a command error indication is placed in the COMMREQ status word. If the channel number is the same as a channel already in use, the channel is 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. If this value is set to 1, only a single transfer will be issued. If this value is set to 0, transfers will be issued on the requested period until the channel is aborted. (Word 10) Time Unit for Send Period: Words 10-11 together define how often the transfer is to be performed (transfer period). Word 10 specifies the time unit such as seconds or minutes for the send period. Word 11 specifies the number of those units. The choices for the time units are shown below. Value Meaning 1 hundredths of seconds single send. A Channel command set up to issue a single send can have only one pending send transfer. Example Send Period Calculation: If Word 10 contains a value of 3 specifying seconds as the time unit and Word 11 contains a value of 20, the send period is 20 seconds. A send is normally issued at the start of each send period. If the pending transfer has not completed during the send period, the Channel Error bit and Detailed Channel Status words are set to indicate a non-fatal period error. The pending transfer can still complete after the period error occurs. For Channel commands set up to issue multiple sends, the next transfer is issued only after the pending transfer completes. If the Number of Time Units is zero, a subsequent transfer is issued as soon as the previous transfer completes. In this case, no period errors are reported by the Channel Error bit. (Word 12) Timeout for Each Send: Word 12 specifies the time (in hundredths of a second) the Ethernet interface will wait for a send transfer to complete before setting
