Description

2 Description The WAGO Programmable Fieldbus Coupler (PFC) teamed with a Horner HMI Device provides a reliable low-cost control system for your automation needs.

Horner Electric provides a variety of options for the HMI requirements of today’s automation system. From fully-featured lowend text displays to color graphics with control capabilities, Horner Electric provides innovative solutions. The WAGO PFC is a powerful full function programmable controller capable of stand-alone control, or distributed control as part of a larger control system. WAGO’s PFC is part of the WAGO-IO-System, a modular fieldbus independent I/O product.

For more information on Horner’s HMI Devices, visit the Horner website at www.heapg.com.

For more information on the WAGO-IO-System, visit WAGO’s website at www.wago.com.

Two options are available for interfacing a Horner HMI Device to the WAGO PFC: The first utilizes WAGO’s 750-650 serial interface module to receive and transmit commands to the Horner device. This solution provides maximum reliability due to vibration-resistant, maintenance-free CAGE CLAMP® connector technology. The second utilizes the configuration port on the front of each WAGO PFC, and is the low-cost alternative. This PFC configuration port provides an RS232 interface capable of baud rates of up to 19200. This solution requires the use of a WAGO Communications Cable (P/N#750-920). Note that this cable Application note A202800

does not provide a retentive connection, making this solution unsuitable for extreme environmental conditions. In each case, the WAGO PFC acts as a Modbus slave to the Horner device, responding to Modbus function calls transmitted serially via RS-232. The attached pages display interconnect drawings and program examples for both solutions.

3.2 Register Mapping for WAGO PFC / Horner HMI Device When using the WAGO PFC function block ‘TERMINAL_MODBUSSLAVE_RTU’ for communications with an HMI device, a data table is maintained within the WAGO PFC. This data table acts as a buffer for data written to and read from the WAGO PFC. Data written by an HMI device to the WAGO PFC is placed in the data table. Data read from the WAGO PFC by an HMI device is read from the data table. The data table occupies 256 words of data, and is shown at right. When an object gets configured in an HMI application, it is given a word or bit value. This word or bit value takes the form of a Modbus register, as shown in the two right most columns of the data table. Each word or bit value corresponds to an element, or WAGO Data Register, in the data table. The contents of the data table must be maintained in the WAGO PFC program. Data to be read by the HMI device needs to be placed in the correct WAGO Data Register(s). Data written by the HMI device needs to be transferred to other WAGO PFC program variable(s) for usage in the PFC program.
