C200H/HX/HG/HE/HS
SYSMAC BUS Error
Flag
(Non-fatal error)
A40205
On when a transmission error occurs in a
data transfer in the SYSMAC BUS system.
The number of the Master involved is
indicated with bits A40500 and A40501.
SR 25312
SYSMAC BUS Master
Error Flags
A40500 to A40501
When an error occurs in the SYSMAC BUS
system, the flag for the affected Master Unit
will be turned ON.
A40500: Flag for Master Unit #0
A40501: Flag for Master Unit #0
SR 25104 to
SR 25115
Slave Number of
SYSMAC BUS Error
After Startup
A42504 to A42506
When there is an error in a Slave Rack, these
bits contain the slave’s unit number.
AR 0200 to AR 0204
correspond to unit
numbers #0 to #4.
p
A42504 only
When there is an error in an Optical I/O Unit
(excluding Slave Racks), the status of
A42504 (0 or 1) indicates whether the Unit is
low or high.
SR 25103
Whether the Unit is
low or high is
indicated in AR 03 to
AR 06.
A42508 to A42515
When there is an error in a Slave Rack, this
byte contains the 2-digit hexadecimal unit
number of the Master to which the Slave is
connected.
(B0 Hex: Master Unit 0; B1 Hex: Master Unit
1)
AR 0015: Error in unit
number #0
AR 0014: Error in unit
number #1
When there is an error in an Optical I/O Unit,
this byte contains the 2-digit hexadecimal unit
number.
(00 to 1F hexadecimal, or 0 to 31 decimal)
AR 03 to AR 06:
These flags turn ON
when there is an error
in the Unit with
corresponding unit
number and status
(L/H).
SYSMAC BUS Slave
Number Refresh Bit
A50900
Turn this bit ON to refresh the error
information in A425 (unit number of Slave
where error occurred after startup).
SR 25100
Allocations in the CIO Area
No CIO Area words are used.
Allocations in the DM Area
No DM Area words are used.
Hardware Setup
1, 2, 3...
1. Mount a Remote I/O Master Unit to a CS1 CPU Rack, a C200H I/O Expan-
sion Rack, or a CS1 Expansion Rack (not a SYSMAC BUS Remote I/O
Slave Rack). Up to two Masters can be mounted for a basic system. (There
are no restrictions on the mounting position.)
2. Set the unit number of the Master using the unit number switch on the front,
and set the CONTINUE/STOP switch as required.
3. Set the unit number, the Output HOLD/STOP Mode, and the type of master
for each of the Slave Units.
4. Set the unit numbers for Slaves other than Slave Units.
5. Perform connections using 2-conductor cable.
6. Set the terminator.
7. Connect a Programming Device to the PC.
