Productivity 1000 Series PLC Modbus ASCII Protocol

More information can be obtained on our website. This includes all of the links mentioned in this video. https://accautomation.ca/productivity-1000-series-plc-modbus-ascii-protocol Modbus is a communication method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Master (Client) and the devices supplying information are Modbus Slaves (Servers). This protocol was originally developed by Modicon systems. Modbus protocol comes in basically three different types. Ethernet (Modbus TCP) or Serial (Modbus RTU or Modbus ASCII). Modbus TCP and Modbus RTU come as standard protocols in the productivity series of PLCs. We will connect the Productivity 1000 PLC to a Solo process temperature controller. This will be done using the Modbus ASCII protocol over serial RS485 communication wire. (Media) The present and set values (PV / SV) will be read from the Solo controller and the set value will be written when required. Let's get started.

Here are just a few. - 50MB user memory - Can handle very complex applications easily. - 4 built-in communication ports – Easy connectivity to your network. - Data logging up to 32 GB on a microSD card - Add up to 8 IP modules to communicate to your field sensors. This will give you a total of 128 discrete IO points or 32 analog IO channels. - Free Software and 30 days of free training with every CPU from Automation Direct. - Interactive PLC Configuration Tool - Tag Names - Auto-discovery IO – Physical I/O tags will be generated based on each module’s position in the base. - I/O Modules have QR codes under the wiring cover. This can be scanned so you can have the latest specifications/wiring diagrams for the module. - Limitless PID – Autotuning – Individual or Cascade Mode - etc - Web Server and Mobile Access - Advanced Software instruction set The Productivity 1000 series of programmable logic controllers currently has all of these features built into the P1-540 CPU. This CPU (Central Processing Unit) is also known as MPU (Multi-Processing Units) because of the communication capabilities. https://www.accautomation.ca
