Corresponding
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.
QnA
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 : Match
ON : Mismatch
• 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.)
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 link are not checked.
• When SM1209 is OFF, the link parameters of the higher
and lower link are checked.
