Unlike conventional PLC I /O, SmartStackT I /O is not a rack-based design. SmartStack I /O modules are snapped onto the Operator Control Station (OCS) or an off-mounted base, and then stacked onto each other.
They utilise a very small amount of panel space for the number of I /O provided. SmartStack modules are encased in metal housings and meet stringent noise, vibration, and shock standards.
A maximum of 4 modules can be stacked directly onto an OCS, and another 20 modules can be added by using the fiber optic FOX I /O System. Color-Touchscreen OCS models can have up to 20 SmartStack modules using the FOX I/O System.
There are over 50 SmartStack I /O modules available.They include a variety of mixed I/O modules offering a combination of inputs and outputs, digital and analog, and specialty modules:
- High Speed Counter (1 MHz),
- Stepper Indexer
- ASCII BASIC
- AC Power Monitoring modules.
You can select from a full complement of temperature input modules (Thermocouple, RTD,Thermistor), and SmartStack communication options include Ethernet TCP/IP, DeviceNetT Master and Slave, PROFIBUS Master and Slave and CANopen Master.
Expansion of SmartStack Modules
You have several ways to expand the number of SmartStack modules. Connecting a miniRCS via the CsCAN port adds one more SmartStack module; networking an RCS controller allows you to add up to 4 more SmartStack modules.
If you use a FOX100 I /O Expansion Module and the FOX I/O System, you can have up to 23 SmartStack modules (3 modules and the FOX100 mounted on the OCS plus 20 modules with the FOX I /O System).
When using a Color-Touch OCS, you may connect 5 bases and have up to 20 SmartStack modules
