5. Special Internal Relays and Special Data Registers for the P/W PC Link
The P/W PC Link status of a network, the CPU status etc. can be checked using special internal relays(R) and spe-
cial data registers(LD).
Refer to page 68, “Monitoring Special Internal Pelays(R) & Special Data Registers(DT)“, for details about the
readout from special internal relays/special data registers.
Checking PC Link Modes(P/W PC LINK 0 : R9060 to R906F, P/W PC LINK 1 : R9080 toR908F)
The following special interal relays can be used for checking whether each station in a network is in PC Link
Mode or not.
ON
: when the station is in the PC Link Mode
OFF : when the station is not in the PC Link Mode
Note :
Checking CPU Mode(RUN or PROG. mode)(P/W PC LINK 0 : R9070 to R907F, P/W PC LINK 1 : R9090
toR909F)
The CPU mode(RUN or PROG.) in the P/W PC Link is checked using the special internal relays.
ON
: when the station is in RUN Mode
OFF : when the station is in PROG. Mode
• Since the P/W PC Link function is available
only for stations assigned as 01 to 16, no
stations outside the range of 01 to 16 can be
checked. If stations outside the range have
in PC Link Mode enabled, an error will
occur.
