Relative Gearing to an External Encoder with a Siemens 1500 PLC

DMC has often encountered a scenario where a customer wants to have a motor drive follow the position of an external encoder. However, a regular 1500 PLC does not allow you to directly gear to an external encoder; this functionality requires a 1500T PLC. The T-series processors allow much more complex motion control, but are also more overhead for simpler projects. As it turns out, with a little creativity, it is possible to gear to an external encoder using a regular 1500 PLC. While you can&...

Commissioning a Siemens G120 VFD with Extended Safety using the Onboard Terminals

DMC recently discovered that there are some unique settings associated with configuring a Siemens G120 Variable Frequency Drive (VFD) with extended safety functionality using the onboard terminals. This blog is meant to be a guide for this type of configuration to avoid troublesome and difficult-to-diagnose issues. Hardware Setup In this particular situation, we used an S7-400H PLC to control a CU240E-2 VFD. The S7-400H can be configured with two CPUs in a fully redundant PLC setup, bu...

Beckhoff TwinCAT3 Scope

For anyone debugging a program, a scope can be an extremely efficient tool for determining the cause of an issue. A scope allows you to monitor a variable (or multiple) in real time, which is a great way of viewing and debugging specific parts of the machine process.  In Beckhoff, TwinCAT 3 offers a very straightforward built-in scope. In this article, I'll detail how to set up a scope to debug a program. Like TwinCAT 3, the TwinCAT 3 Scope is integrated into...

Connecting to Legacy Telemecanique XBT Terminals

As legacy hardware begins to fail, support can be difficult for a variety of reasons - not the least of which is the deprecation of programming software and debugging tools. I recently helped a customer restore the program to an old Telemecanique (now owned by Schneider Electric) XBT-C terminal, and wanted to pass along some lessons I learned. This guide will be for the XBT-C series terminals, but should be similar to other legacy devices as well. Getting Started First and foremost, you wi...

Industrial Security: 4 Ways to Keep Your Factory Safe from Cyber Attacks

Two years ago, I had the opportunity to meet a high-ranking US Senator. One thing that stuck with me was how seriously he took Chinese cyber espionage. Was it really possible that our phones could spy on us, even when powered down, unless the battery is removed? I was skeptical, but since then, we’ve learned of the reality of incurable spyware that lives on your hard drive’s firmware, and seen countless high-profile cyber-attacks that can bring even the largest companies to their ...
