CPU
M9200 SM1200
ZNRD instruction
(LRDP instruction
for ACPU)
reception (for
master station)
OFF: Not accepted
ON : Accepted
• 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.
M9201 SM1201
ZNRD instruction
(LRDP instruction
for ACPU)
completion (for
master station)
OFF: Not completed
ON : End
• 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.
M9202 SM1202
ZNWR instruction
(LWTP instruction
for ACPU)
reception (for
master station)
OFF: Not accepted
ON : Accepted
• 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.
M9203 SM1203
ZNWR instruction
(LWTP instruction
for ACPU)
completion (for
master station)
OFF: Not completed
ON : End
• 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.
M9204 SM1204
ZNRD instruction
(LRDP instruction
for ACPU)
reception (for local
station)
OFF: Not completed
ON : End
On indicates that the ZNRD instruction is complete at the
local station.
M9205 SM1205
ZNWR instruction
(LWTP instruction
for ACPU)
recep-tion (for
local station)
OFF: Not completed
ON : End
On indicates that the ZNWR instruction is complete at the
local station.
M9206 SM1206
Host station link
parameter error OFF: Normal
ON : Abnormal Depends on whether or not the link parameter setting of
the host is valid.
M9207 SM1207
Link parameter
check results OFF: YES
ON : NO
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.)
M9208 SM1208
Sets master
station B and W
transmission
range (for lower
link master
stations only)
OFF: Transmits to tier2 and
tier 3
ON : Transmits to tier2 only
• 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.
M9209 SM1209
Link parameter
check command
(for lower link
master stations
only)
OFF: Executing the check
function
ON : Check non-execution
• 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.
M9210 SM1210
Link card error (for
master station) OFF: Normal
ON : Abnormal Depends on presence or absence of the link card
hardware error. Judged by the CPU.
M9211 SM1211
Link module error
(for local station
use)
OFF: Normal
ON : Abnormal Depends on presence or absence of the link card
hardware error. Judged by the CPU.
M9224 SM1224 Link status
OFF: Online
ON : Offline,station-to-station
test, or self-loopback
test
Depends on whether the master station is online or offline
or is in station-to-station test or self-loopback test mode.
M9225 SM1225 Forward loop error
OFF: Normal
ON : Abnormal
Depends on the error condition of the forward loop line.
M9226 SM1226 Reverse loop error
OFF: Normal
ON : Abnormal
Depends on the error condition of the reverse loop line.
M9227 SM1227 Loop test status
OFF: Not being executed
ON : Forward or reverse loop
test execution underway
Depends on whether or not the master station is executing
a forward or a reverse loop test.
M9232 SM1232
Local station
operation status
OFF: RUN or STEP RUN
status
ON : STOP or PAUSE status
Depends on whether or not a local station is in STOP or
PAUSE mode.
