In this TechTip, we're looking at using dynamic limits in numeric objects, alarm colours, and using a macro to calculate the limits based on a +/- tolerance.

In the demo program, the "Actual" value is in LW-0, the "Target" is in LW-2, "Tolerance" in LW-4 and LW-10 & LW-12 are Lower and Upper limits respectively.

The macro code deals with the case of a 0 target, and also negative target and negative limits:

macro_command main()

float target = 0 //…

EtherNet/IP is a leading industrial protocol supported by many PLCs and controllers, with this in mind, Weintek has added EtherNet/IP protocol support to their remote I/O coupler module, iR-ETN, allowing iR Series remote I/O to support EtherNet/IP.

EtherNet/IP Communication Modes
EtherNet/IP provides two communication modes to address different demands.

EtherCAT^® (Ethernet for Control Automation Technology) is an Ethernet-based industrial Fieldbus system that delivers high-performance, high-immediacy communication, with the growing popularity, Weintek has added EtherCAT support for their built-in CODESYS^® products. Together with the iR-ECAT and various I/O modules, they form a complete EtherCAT solution where the Weintek CODESYS HMI or PLC serves as an EtherCAT master and iR-ECAT are EtherCAT slaves.

Lightweight and affordable, 7” HMI have been widely adopted in many different industries and are a firm favourite. With this in mind, Weintek have released new 7” HMI models in the cMT X Series range: cMT3072X and cMT3072XH (“cMT3072X(H)”) to help users with IIoT integration in their smart factories whilst also providing exceptional user experience.

cMT3072X(H) is equipped with a quad-core 64-bit Cortex A35 CPU, a big performance step up from the dual-core 32bit processor of the existing cMT3071/cMT3072…

Product Introduction
As the Industrial 4.0 revolution gathers pace, users are eagerly searching for ways to retrofit legacy factory installations with smart capabilities. To help with this, Weintek have integrated their CODESYS and IIoT Gateway into a single product, the cMT-CTRL01 - IIoT Programmable Logic Controller. This new model with built-in CODESYS, in addition to working with all iR modules also features IIoT Gateway protocol translation and the EasyAccess remote access service, making it…

Having invested heavily in research to develop an easy-to-use, integrated motion control solution, Weintek have launched the iR-PU01-P, a single axis motion control module to their iR Series of remote i/o. This new module works with existing iR Series communication couplers to control stepper/servo motors, making it great for applications requiring positioning control, such as packaging and filling machines, measurement systems, printing machines, tension controllers and conveyor systems.
