ZNRD instruction
(LRDP instruction
OFF: Not accepted
for ACPU)
ON : Accepted
reception (for
master station)
• 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.
ZNRD instruction
(LRDP instruction
for ACPU)
completion (for
master station)
ZNWR instruction
(LWTP instruction
for ACPU)
reception (for
master station)
• 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.

Host station link
parameter error
On indicates that the ZNRD instruction is complete at the
local station.
OFF: Not completed
ON : End
On indicates that the ZNWR instruction is complete at the
local station.
OFF: Normal
ON : Abnormal
OFF: Normal
ON : Abnormal
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 only for the master stations 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 links are not checked.)
• When SM1209 is OFF, the link parameters of the higher
and lower links are checked.
Depends on presence or absence of the link card
hardware error. Judged by the CPU.
OFF: Normal
ON : Abnormal
Depends on presence or absence of the link card
hardware error. Judged by the CPU.

• 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.

QnA
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.
Depends on whether or not a local station is in STOP or
PAUSE mode.
