Data Acquisition System Using the MX100
System Components, Module Numbers, and Channel Numbers
System Components
A data acquisition system using the MX100 consists of the data acquisition unit
(hereinafter, the MX100), a PC, and a device for connecting to a network. A single MX100
comprises a "main module" with an Ethernet port, "input/output modules" for signal I/O,
and a "base plate" for mounting and connecting these components.

Module Numbers
The module numbers assigned to the input/output modules are those of the slot number
in which the modules are installed. The slot numbers are 0, 1, 2, 3, 4, and 5. If a module
occupies more than one slot, its module number is the lowest slot number that it
occupies.
Example: The module number of a 30-CH, Medium-Speed DVC/TC/DI Input Module
occupying slots 2, 3, and 4 is "2."

1–10
11–20
21–30
31–40
41–50
51–60
Channel numbers in the unit
For 4 ch modules, the last digit is 1 to 4
For 6 ch modules, the last digit is 1 to 6
For 8 ch modules, the last digit is 1 to 8

Channel Numbers
Channels are specified by the channel numbers in the unit. The channel numbers in the
unit are determined by the slot number of the module (slot position in the unit) and the
channel of that module (the terminal position in the module).
Example: For a module installed in slot 3, its number 2 channel is assigned channel
number "32" in the unit.
Note
On the MX100 Standard and MXLogger software programs by Yokogawa, the channel numbers
are expressed as 5-digit numbers consisting of the unit number and the channel number in the
unit. However with the API, communication takes place by specifying the IP address, therefore
only the channel number in the unit is used as the channel number.
