●●Types of Units
In the SYSMAC CJ Series, Units are classified into the following three types. The number of Racks differs depending on the type.
Type | Appearance (example) | Description | Unit recognition method | No. of units |
|
|
|
|
|
Basic I/O Units |
| Units with contact inputs and contact outputs. | Recognized by the CPU Unit according | No restrictions. |
|
|
| to the position of the Rack and slot. |
|
Special I/O | Special I/O Units provide more advanced functions | Recognized by the CPU Unit according | A maximum of 96 Units can |
Units | than do Basic I/O Units, including I/O other than | to the unit number (0 to 95) set with the | be connected. (Multiple unit |
| contact inputs and contact outputs. | rotary switches on the front panel. | numbers are allocated per Unit, |
| Examples of Special I/O Units are Analog I/O Units |
| depending on the model and |
| and |
| settings.) |
| CPU Bus Units (including Network Communications |
|
|
| Units) in having a smaller area for exchanging data |
|
|
| with the CPU Unit. |

CPU Bus Units | CPU Bus Units exchange data with the CPU Unit | Recognized by the CPU Unit according | A maximum of 15 Units can be |
