PLC Processing and Industrial Network Functions

The 07KT98 executes PLC control logic while managing onboard digital and analog signals. It supports two EIA RS-232 ports for programming and debugging, while the CS31 EIA RS-485 interface connects distributed I/O devices. In addition, the integrated ARCNET interface supports peer-to-peer controller communication.

The configurable I/O channels allow the unit to handle mixed signal requirements. Analog inputs accept voltage, current, and Pt100 sensor signals, while analog outputs provide voltage or current signals. Furthermore, the integrated high-speed counter supports frequencies up to 50 kHz across seven operating modes.

Frequently Asked Questions

Q: Can the 07KT98 operate without remote I/O modules?
A: Yes. The supplied specifications identify the unit as capable of standalone PLC operation with integrated onboard I/O.

Q: Which communication interfaces are integrated into the 07KT98?
A: The unit provides two EIA RS-232 ports, one EIA RS-485 CS31 system bus interface, and an ARCNET interface through a BNC connector.

Q: What signal types can the analog channels process?
A: The eight analog inputs support 0-10 V, +/-10 V, 0-20 mA, and Pt100 configurations. The four analog outputs support +/-10 V, 0-20 mA, and 4-20 mA.

Field Installation Guidelines

• Mount the unit securely on the designated controller installation structure and maintain access to all connectors.
• Route RS-232, CS31, ARCNET, digital, and analog signal cables separately where practical to reduce electrical interference.
• Use appropriate shielded cabling for communication and low-level analog signals.
• Terminate cable shields according to the AC31 installation design and site grounding practice.
• Verify the 24 VDC supply polarity and voltage before energizing the unit.
• Check the maximum output loading before connecting field devices to transistor outputs.
• Keep analog signal wiring away from high-current switching conductors and motor cables.
• Inspect the BNC connection and CS31 wiring for secure mechanical engagement before commissioning.
• Back up application programs and configuration data using the supported SmartMedia card function where required.
• Confirm I/O addressing and signal configuration before placing the PLC into automatic operation.
