Personal Computer Connection Example
In this example, communications between the CPU Unit and the personal
computer are continued even after an operation switching error occurs.
interrupted, so enable communications retries in the personal computer
(SCADA software, etc.) communications settings.
In a CS1D Duplex System, a duplex power supply can be configured by
mounting a pair of CS1D Power Supply Units on the CPU Rack, an Expansion
Rack, or Long-distance Expansion Rack.
With a duplex power supply, the Backplane’s 5-V DC/26-V DC power supply is
provided from the two CS1D Power Supply Units. Therefore the load per
CS1D Power Supply Unit is approximately 50%.
If there is a breakdown at one of the CS1D Power Supply Units, operation is
continued by using only the other one. In that event, the load at the one
remaining CS1D Power Supply Unit will increase to 100%. (See note 1.) At
the same time, A31602 (duplex power supply error) will turn ON.
Errors at Power Supply Units mounted on any Rack can be checked by means
of A31900 to A31915 (for 5-V/26-V output errors) or A32000 to A32015 (for
primary-side input voltage errors).

the transmission path must therefore be 50 m or less. If the trans-
mission distance is greater than 50 m, use the NT-AL001, which
provides isolation, and do not include the CJ1W-CIF11 in the
transmission path. When only the NT-AL001 is used, the total
length of the transmission path can be a maximum of 500 m.
