Nomenclature
I/O Assist Server Unit:
The I/O Assist Server Unit supports the management function that enables it to collect data from, and
set data to, I/O controller units that belong to the same group as the Group ID that is set by using the
Group ID switches of the SVR-IOAxx(FIT)GY ("Assist Server"), which is a CONTEC product.
Group IDs can be set in a range of 0 - 7.
By connecting local terminals and office terminals by means of a Web browser, it is possible to
monitor the status of the devices that are connected to an I/O controller unit.
I/O Controller Unit:
The I/O Controller Unit is a general term that refers to any combination of this product, the
CPU-CAxx(FIT)GY, with device modules.
Each device contains a Group ID SW and a Unit ID SW; these switches must be set so that they are
unique within the network. The I/O Controller Unit transmits data collected from the devices to the
I/O Assist Server Unit that bears a specified Group ID.
The Group ID for a CPU-CA10(FIT)GY can be set in the range 0 - 8. The Unit ID can be set in the
range 0 - 7.
The Group ID for a CPU-CA20(FIT)GY can be set in the range 0 - 8 and A. The Unit ID can be set in
the range 0 - 7. If the Group ID is set to A, the Unit ID can be set in the range 0 - 7Fh, permitting up
to 128 devices.
Data cannot be sent to an I/O Assist Server if the Group ID is set to 8 or A. Control of the I/O
controller unit can be performed directly from a terminal.
Further details on this topic may be found in the respective device module manuals.
