I have worked on Siemens S7-300 PLC and used Siemens TIA Portal software to develop programs.

• Siemens S7-300 PLC

• Siemens TIA Portal software

The Micrologix 1400 can support up to 6 types of analog signals.

• The Micrologix 1400 can handle analog signals such as voltage, current, resistance, thermocouples, RTDs, and potentiometers.

• It has 6 analog inputs that can be configured for different types of signals.

• For example, you can use one input for a voltage signal and another input for a thermocouple signal.

• The analog signals can be used for monitoring and control...read more

There are several types of 4-20 mA type transmitters used in automation engineering.

• Some common types include pressure transmitters, temperature transmitters, level transmitters, and flow transmitters.

• Each type of transmitter is designed to measure a specific parameter and convert it into a 4-20 mA current signal.

• For example, a pressure transmitter measures the pressure of a fluid or gas and converts it into a 4-20 mA ...read more
