Page 21 Communications Methods This section briefly describes the supported communications methods and how to wire equipment. Refer to this section when setting up equipment. 1-1 Overview of Communications Methods ......1-2 1-1-1 Introduction .
Page 22 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 1 Communications Methods Communications baud rate, data length, stop bits and vertical parity can each be set independently in the communications setting level. Highlighted values indicate default settings. 1-1-3 Transmission Procedure When the host transmits a command frame, the E5@D transmits a response frame that corresponds to the command frame.
Page 24 1 Communications Methods 1-1-5 Wiring RS-485 • The RS-485 connection can be either one-to-one or one-to-N. Up to 32 units including the host can be connected in a one-to-N system. • The total cable length is 500 m max. • Use shielded twisted-pair cable. For detailed wiring specifications, refer to Precautions for Safe Use on page 7.
Page 25 1 Communications Methods 1-1-6 Communications Parameters The E5@D's communications specifications are set in the communications setting level. These param- eters are set on the E5@D's front panel. The following table shows the communications parameters and their setting ranges. Item Code Settings Set Values Communications protocol...
Page 26 1 Communications Methods 1-1-7 Communications Parameter Setup Before you carry out communications with the E5@D, set up the communications unit number, baud rate, and other parameters by carrying out the following procedure.

Page 76 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 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 77 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.

Page 110 6 Programless Communications 6-5 Connecting to CJ-series PLCs ........6-33 6-5-1 Configuration and Procedure .
Page 111 6-1-2 Features • You can connect to an OMRON CS/CJ-series, CP-series, NJ-series, or NX1P2 PLC, to a Mitsubishi Q-series, L-series, FX-series, or iQ-R-series PLC, or to a Keyence KV-series PLC. • Up to 13 E5@D parameters can be assigned for reading and up to 13 E5@D parameters can be assigned for writing in PLC memory.
Page 112 6 Programless Communications 6-1-3 Operation for Programless Communications Programless communications are performed in the following order of communications unit numbers. 0 (master) → 1 → 2 → ... → Highest communications unit number → 0 → 1... The master (the Controller with communications unit number 0) starts programless communications approximately five seconds after the power supply to it is turned ON.
Page 113 6 Programless Communications 6-1-5 Connectable PLCs The PLCs that can be connected are given below. For PLCs that are not listed in the following tables, you can use the upload settings and download set- tings for Modbus communications as an alternative method to achieve efficient communications. (These communications are not programless.) For details, refer to 4-5 Upload Settings and Download Settings for Modbus Communications.

Refer to 6-1-5 Connectable PLCs for lists of the PLCs that can be connected.
Page 116 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 Controllers and the PLC.
Page 117 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 Controllers. Make sure that setting of the Highest Communications Unit No. parameter agrees with the unit num- bers of the E5@D Controllers that are actually connected.
Page 118 6 Programless Communications Note: If more than one E5@D Controller is connected to the same communications line, set the starting address to the same value for all of them. The E5@D Controller with communications unit number 0 will use the words that start from the specified starting address, the E5@D Controller with unit number 1 will use the words that start from the specified starting address plus 30 words, and the E5@D Controller with unit number 2 will use the words that start from the specified starting address plus 60 words...
