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@D-H 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, debris (such as cuttings) from installation work, moisture, or other foreign matter to enter the Digital Controller, the Setup Tool ports, or between the pins on the connectors on the Setup Tool cable.
Page 8: Security Measures
Safety Precautions CAUTION 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. A malfunction in the Digital Controller may occasionally make control operations impossible or prevent alarm outputs, resulting in property damage.
Page 9: Safety Standards
Safety Precautions Safety Standards CAUTION - Risk of Fire and Electric Shock (a)This product is UL listed as Open Type Process Control Equipment. It must be mounted in an enclosure that does not allow fire to escape externally. (a)More than one disconnect switch may be required to de-energize the equipment before servicing.
Page 10: 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. Do not handle the Digital Controller in ways that exceed the ratings. ( 1 ) The product is designed for indoor use only.
Page 11 Precautions for Safe Use (10) Make sure that the Digital Controller has 30 minutes or more to warm up after turning ON the power before starting actual control operations to ensure the correct temperature display. (11) When using adaptive control, turn ON power for the load (e.g., heater) at the same time as or before supplying power to the Digital Controller.
Page 12 Precautions for Safe Use (30) Noise may enter on the USB-Serial Conversion Cable, possibly causing equipment malfunctions. Do not leave the USB-Serial Conversion Cable connected constantly to the equipment. (31) With the E5ED-H, do not connect cables to both the front-panel Setup Tool port and the top-panel Setup Tool port at the same time.

Page 22: 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 23: Transmission Procedure
1 Communications Methods 1-1-3 Transmission Procedure When the host transmits a command frame, the E5@D-H 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 80: Modbus Communications Procedure
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@D-H 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 81 4 Modbus Communications Procedure (7) The result of the CRC calculation (value in the CRC register) is appended to the last byte of the message. • Example of Appending the Calculation Result When the calculated CRC value is H'1234, the CRC value is appended to the command frame as follows.

Page 122: Communications Unit No. And Communications Baud Rate
6 Programless Communications 6-2-2 Communications Unit No. and Communications Baud Rate Always assign communications unit numbers in order starting from 0. Do not skip any numbers. The recommended communications baud rate is 38.4 for a Mitsubishi FX3 PLC and 115.2 for other PLCs. Set the same communications baud rate for all of the E5D-H Controllers and the PLC.
Page 123: Highest Communications Unit No
6 Programless Communications 6-2-5 Highest Communications Unit No. Set the Highest Communications Unit No. parameter to the highest communications unit number that is actually set on the connected E5@D-H Controllers. Make sure that setting of the Highest Communications Unit No. parameter agrees with the unit num- bers of the E5@D-H Controllers that are actually connected.
Page 124 6 Programless Communications Note If more than one E5@D-H Controller is connected to the same communications line, set the starting address to the same value for all of them. The E5@D-H Controller with communications unit number 0 will use the words that start from the specified starting address, the E5@D-H Controller with unit number 1 will use the words that start from the specified starting address plus 37 words, and the E5@D-H Controller with unit number 2 will use the words that start from the specified starting address plus 74 words...
