Details
• Depends on whether or not the ZNRD (word device read)
instruction has been received.
• Used in the program as an interlock for the ZNRD
instruction.
• Use the RST instruction to reset.
• Depends on whether or not the ZNRD (word device read)
instruction execution is complete.
• Used as a condition contact for resetting M9200 and
M9201 after the ZNRD instruction is complete.
• Use the RST instruction to reset.
• Depends on whether or not the ZNWR (word device
write) instruction has been received.
• Used in the program as an interlock for the ZNWR
instruction.
• Use the RST instruction to reset.
• Depends on whether or not the ZNWR (word device
write) instruction execution is complete.
• Used as a condition contact to reset M9202 and M9203
after the ZNWR instruction is complete.
• Use the RST instruction to reset.
• On indicates that the ZNRD instruction is complete at the
local station.
• On indicates that the ZNWR instruction is complete at the
local station.
• Depends on whether or not the link parameter setting of
the host is valid.
• Depends on whether or not the link parameter setting of
the master station in tier two matches that of the master
station in tier three in a three-tier system.
(Valid for only the master station in a three-tier system.)
• Depends on whether or not the B and W data controlled
by higher-link master station (host station) is sent to lower-
link local stations (tertiary stations).
When SM1208 is OFF ............ B and W of host station is
sent to tertiary stations.
When SM1208 is ON.............. B and W of host station is
not sent to tertiary stations.
• Set to ON not to match B and W of the higher and lower
links.
• When SM1209 is ON, the link parameters of the higher
and lower link are not checked.
• When SM1209 is OFF, the link parameters of the higher
and lower link are checked.
Control is performed depending on whether the link card
hardware is faulty or not.
Control is performed depending on whether the link card
hardware is faulty or not.
Depends on whether the master station is online or offline or
is in station-to-station test or self-loopback test mode.
Depends on the error condition of the forward loop line.
Depends on the error condition of the reverse loop line.
Depends on whether or not the master station is executing a
forward or a reverse loop test.
Control is performed depending on whether a local station is
in the STOP or PAUSE mode.
Depends on whether or not a local station has detected an
error in another station.
