Product Details
Interface development is based on the ABB Panel Builder configuration tool (3BSE042236R2 PP865A). This tool is similar to a Windows operating environment, with rich built-in templates and graphics libraries, and supports multilingual display, greatly simplifying the configuration and debugging process of HMI projects. It is equipped with Ethernet, RS-232, and RS-485 interfaces, supporting simultaneous connection of 3 PLCs and 2 remote I/O modules, meeting the distributed control needs of large-scale equipment.
It supports mainstream industrial protocols such as Modbus, OPC, and PROFIBUS, and is also compatible with Ethernet/IP communication protocols, allowing seamless integration with ABB AC800M controllers and third-party industrial equipment.
Cable and Bus Termination RS-485：
• Use shielded and twisted pair cable. The pair capacitance may not exceed 52.5 pF/m, and the area must be at least 0.25 mm² (AWG 24), if you want to use the maximum transfer distance and maximum transfer speed.
• 0 V, the reference voltage for communication should be included in the cabling. With two-way communication, use two pairs; one pair for communication and one pair for 0 V.
• The shield must be grounded at one end. The other end is usually grounded, but with longer distances or when there is a difference in the ground potential, the shield should be connected to the ground via a 0.1 μF/250 V plastic capacitor to prevent ground current in the braided shield. Several manufacturers recommend that the shield be grounded at each node.
Various manufacturers have different systems for bus termination. The RS-485 standard does not describe how the "Fail Safe" function would be carried out, just that the system should be able to handle the error.
Depending on the recipients' design, the bus wires may be on the same level or require pull-up or pull-down to ensure that no faulty signals are detected when the bus is in resting mode (all transmitters are disconnected).
1. Some (older) operator panels had pull-up and pull-down resistance except for the actual bus termination at 120ohmsm, similar to Westermo and Profibus.
2. Newer panels have another type of recipient, so-called built-in "Fail Safe", where simple bus termination resistance is sufficient.
If other nodes on the RS-48585 network require pull-up and pull-down, and the operator panel is at one end of the loop, one of the following procedures can be carried out:
3. Connect two 1 ohm/0.25 W resistors in the 25-pole D-sub contact. Set jumper pins 6-19.
