    Safety Precautions Safety Precautions Definition of Precautionary Information The following notation is used in this manual to provide precautions required to ensure safe usage of the E5@C-T Digital Controllers. The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.
  • Page 7 Safety Precautions  Safety Precautions CAUTION Minor injury due to electric shock may occasionally occur. Do not touch the terminals while power is being supplied. Electric shock, fire, or malfunction may occasionally occur. Do not allow metal objects, conductors, cuttings from installation work, or moisture to enter the Digital Controller or a Setup Tool port.
  • Page 8 Safety Precautions CAUTION Loose screws may occasionally result in fire. Tighten the terminal screws to the specified torque of 0.43 to 0.58 N·m. Set the parameters of the product so that they are suitable for the system being controlled. If they are not suitable, unexpected operation may occasionally result in property damage or accidents.

  • Page 9: Precautions For Safe Use

    Precautions for Safe Use Precautions for Safe Use Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on the performance and functions of the product. Not doing so may occasionally result in unex- pected events. Use the product within specifications. •...
  • Page 10 Precautions for Safe Use • Design the system (e.g., control panel) considering the 2 seconds of delay in setting the Digital Controller’s output after the power supply is turned ON. • The output will turn OFF when you move to the initial setting level. Take this into consideration when performing control.

  • Page 20: Overview Of Communications Methods

    CompoWay/F is OMRON's standard communications format for general serial communications. This format uses a standard frame format as well as the well-established FINS* commands used for OMRON's PLCs. Therefore, it can simplify communications between components and the host. FINS (Factory Interface Network service) The FINS protocol provides message communications between controllers in OMRON FA networks.

  • Page 21: Transmission Procedure

    1 Communications Methods 1-1-3 Transmission Procedure When the host transmits a command frame, the E5@C-T transmits a response frame that corresponds to the command frame. A single response frame is returned for each command frame. The following diagram shows the operation of the command and response frames. Command frame Command frame Host...

  • Page 82: Data Format

    4 Modbus Communications Procedure Data Format The data format complies with the Modbus (RTU) communications protocol, so commands from the host and responses from the E5@C-T are contained in data blocks called frames. The structure of the command and response frames is described below. In the following explanations, hexadecimal values are expressed by adding the prefix H' before the number, e.g., H'02.
  • Page 83 4 Modbus Communications Procedure  CRC-16 Calculation Example Messages are processed one byte at a time in the work memory (a 16-bit register known as the CRC register). (1) The CRC register is initialized to H’FFFF. (2) An XOR operation is performed on the content of the CRC register and the first byte of the message, and the result is returned to the CRC register.

To perform component communications, change the parameter settings in the communications setting level to the values that are given below.
  • Page 173 7 Component Communications SP Calculations (Fixed-value Controllers Only) The set point of a slave can be calculated from the fixed SP or program SP of the master as shown below. The slave performs the calculation only during operation. The value is not written to the slave if it exceeds the set point limiter.

    7 Component Communications Operation for Component Communications Only two items can be sent from the master to the slaves: the fixed SP or program SP, and the RUN/RESET status. If the set point or the RUN/RESET status is changed at the master, the new value is sent to the slaves starting with the slave with communications unit number 1 and continuing on to the slave with the high- est communications unit number.
