A wide range of Horner Automation controllers were used during the project. For example, the XL6, EXL6e, XL7e, EXL10e, & SmartMods. The main reason such a range of controllers was needed was down to the different screen sizes of the ovens. The controllers were also used due to their wide range of I/O. For example, the XL7e has two Ethernet ports and so does the EXL10e. This means the controllers have HTTP (Envision RV), FTP (Envision FX) and WebMI capabilities.
Another useful feature of the controller is the communication features. For example, EXL6e, XL7e, EXL10e all have RS-232 & RS-485; RS-232/RS-485 ports, PLC /Drive protocols. They also have USB ports and RTU/Modbus/Master/Slave/Serial ASCII In/Out.
Thanks to datalogging, recipes in a .csv format, Modbus TCP and WebMI the oven is Industry 4.0 compliant.
Scada communication over Ethernet with Modbus TCP protocol is a requirement for many customers. Modbus RTU is used to control the IOs and the frequency drives. This is important because Scada is a system manager that can allow for a plant to be monitored remotely, usually on Intranet. Modbus TCP protocol is one of the communication protocols available on SCADA packages. Modbus RTU is, in this case, to control the Oven Remote I/O and frequency drives.
The Cscape programming to complete this project was advanced ladder. The other Horner software used during the project was WebMI.
