8.2 Reading/Writing Routing Information
Reading routing information
S(P).RTREAD
Processing details
• Reads data from transfer destination network number specified by n, using routing information set by the routing
parameters, and stores it into the area starting from (D).
• If no data for the transfer destination network number specified by n is set at the routing parameters, stores 0 into the area
starting from (D).
• The contents of the data stored in the area starting from (D) is as indicated below.
[Specification range of relay station number]
Operation error
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
• LCPU: The serial number (first five digits) is "13012" or later.
n: Transfer destination network No. (1 to 239) (BIN 16 bits)
(D): Head number of the devices that stores the read data (Device name)
