3.0 REMOTE I/O NETWORK
COMMUNICATIONS
(RERIO)
Loading the Remote I/O software (RERIO) onto the PC Link module
allows it to monitor all drops on a remote I/O network, accessing the
output data being sent from the Master to the Slave drops as well as
the input data being sent from the Slave drops back to the Master.
The PC Link module may also be configured as an active drop which
will receive output data from the Master and send input data back to
the Master. The PC Link module can act as any valid drop and can
have any valid drop depth.
3.1 RERIO Memory Organization
The RERIO memory is a 16K block starting at offset 0 in the installed
segment. Although 16k is available, not all of it is used. Any
references to card memory in this appendix assume the installed
segment address. The memory organization of the PC Link module
running the RERIO software is summarized in Table 3.
