We've demonstrated Modbus RTU & Modbus TCP functionality in IEC-61131 before - it's a very popular video. In that session we gave you a ton of useful information - but we dealt strictly with Modbus integer (INT) data. Modbus devices often transmit DINT and REAL data values packed in a package of multiple integers. And
In many motion control applications, a Horner OCS and a SmartMotor provide an unbeatable combination – especially in those applications where space is at a premium. For the OCS connection to the SmartMotor – there are a variety of options including old school step & direction and Modbus TCP. But this week we’ll make the
Modbus is the de facto standard when it comes to industrial connectivity in a multi-manufacturer automation environment. Modbus is an address-based protocol based on a traditional PLC. But with IEC-61131, register addresses are a foreign concept as IEC 61131 is strictly variable-based. What gives? In this session we’ll not only talk about how to implement
What are the differences between Ethernet IP & Modbus TCP? How are they similar? What is Ethernet Global Data – and what can it be used for? Join us as we explore two of the most popular Industrial Ethernet protocols – and a third that deserves to be more popular than it is. Join us
Communications is one of the strengths of the Horner OCS. Another strength is distributed control – where a complex control task can be modularized to provide efficiency and scalability in the application by utilizing multiple OCS controllers. But what communications architecture and which communications protocol(s) should you use? In this session we’ll dive into the
Modbus remains the de facto standard for communications between devices from multiple manufacturers. But Modbus is a register-based protocol - how do we apply it in a variable/tag-based logic environment? We will explore this, and provide you with practical guidance when utilizing this versatile protocol, even as you modernize your programming approach. WATCH NOW...
