1 Communications Methods 1-1 Overview of Communications Methods 1-1-1 Introduction The program for the communications functions is created on the host (personal computer, PLC, or other type of communications master), and the E5@C-T's parameters are monitored or set from the host. Therefore, the description provided here is from the viewpoint of the host. CompoWay/F is OMRON's standard communications format for general serial communications.
1 Communications Methods 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.
1 Communications Methods 1-1-6 Communications Parameters The E5@C-T's communications specifications are set in the communications setting level. These parameters are set on the E5@C-T's front panel. The following table shows the communications parameters and their setting ranges. Item Communications protocol setting Communications unit No.
1 Communications Methods Description of Communications Parameters When communications parameter settings have been changed, the new settings must be enabled by resetting the Controller. • Protocol Setting (psel) The communications protocol can be selected.

4 Modbus Communications Procedure 4-1 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. Numbers and alphabetic characters without the H' prefix are ASCII characters.
4 Modbus Communications Procedure z 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. (3) The MSB is packed with zeroes and the CRC register is shifted 1 bit to the right.
4 Modbus Communications Procedure 4-1-2 Response Frame z Normal Response Frame Slave address Function code 1 1 Data CRC-16 2 bytes CRC-16 calculation range z Error Response Frame Slave address Function code 1 1 Error code 1 CRC-16 2 bytes CRC-16 calculation range Slave address Function code Error code CRC-16 4-4 The number specified in the command frame is entered as-is. This is the unit number of the Unit returning the response.
4 Modbus Communications Procedure 4-1-3 Error Codes End code H'01 H'02 H'03 Operation error Description An unsupported function code was received. The specified variable area address is out-of-range. The amount of data does not match the number of elements. The byte count is not 2 times the number of elements. The response length exceeds the size of the communications buffer. The command code or related information in the operation command is wrong or the write data is not in the setting range.
4 Modbus Communications Procedure 4-2 Function List The following table lists the function codes. Function Code List Function code 03 (H'03) 16 (H'10) 4-6 Name Read variable (multiple) Write variable (multiple) 06 (H'06) Write variable (Single/operation command) 08 (H'08) Echoback Test Process This function reads from the variable area. It is possible to read two or more consecutive variables. This function writes to the variable area. It is possible to write two or more consecutive variables.
4 Modbus Communications Procedure 4-3 Variable Area The variable area is the region of memory used to exchange data with the E5@C-T through communications. Operations such as reading the process value and reading/writing parameters are performed on the variable area. On the other hand, operation commands do not use the variable area.
4 Modbus Communications Procedure 4-4 Detailed Description of the Services 4-4-1 Variable Read, Multiple To read from the variable area, set the required data in the command frame, as shown in the following diagram. Command Frame Slave address Function code Read start address Number of Elements CRC-16 H'03 1 1 Name Slave address Function code Read start address Number of elements CRC-16 4-8 2 2 2 bytes Description Specify the E5@C-T's unit number.
4 Modbus Communications Procedure Response Frame Slave address Function code Read data (for the number of elements) Byte count CRC-16 H'03 0 to 212 (2 × 106) 1 Name Slave address Function code 2 Description The value from the command frame is entered as-is. This is the received function code. When the function ended normally, the function code is left as-is. When an error occurred, the hexadecimal value of H'80 is added to the function code to indicate that the response is an error response.
4 Modbus Communications Procedure 4-4-2 Variable Write, Multiple To write data to the variable area, set the required data in the command frame, as shown in the following diagram.
4 Modbus Communications Procedure z Response Frame Slave address Function code Write start address Number of Elements CRC-16 2 2 2 bytes H’ 10 1 Name Slave address Function code 4-4 Detailed Description of the Services 1 Description The value from the command frame is entered as-is. This is the received function code. When the function ended normally, the function code is left as-is.
4 Modbus Communications Procedure Writing Undisplayed Parameters It is possible to write the parameters that are not displayed due to display settings as well as the parameters that are never displayed in the Controller. • Example Command and Response The following example shows the command/response when writing the Alarm Value Upper Limit 1 and Alarm Value Lower Limit 1 parameters. (In this case, the slave address is H'01.

6 Programless Communications 6-1 Programless Communications 6-1-1 Introduction With programless communications you can read and write E5@C-T parameters or start and reset the E5@C-T from a Programmable Controller (PLC). Communications with the PLC are performed automatically by the E5@C-T, so there is no need to program communications. The E5@C-T automatically reads and writes PLC memory. E5CC-T No.0 25 0 C E5CC-T No.2 C 25 E5CC-T No.n C 25 0 0 6-1 Programless Communications C E5CC-T No.
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. (Communications are not performed until the power supply to the master is turned ON.

All of these parameters are displayed if you set the Protocol Setting parameter to cmp. (Some of the parameters are always displayed.) This section describes the parameters that are used to calculate the set point. The other parameters are the same as for programless communications. Refer to 6-2 E5@C-T Controller Setup.
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 7-2 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 highest communications unit number. The master sends values only during operation.
7 Component Communications 7-3 Troubleshooting Possible problems that can occur with component communications and corrective actions are given in the following table. Status The set point or RUN/RESET status will not change for a slave (i.e., a Controller with a communications unit number other than 0). The set point is not calculated. It is sometimes not possible to change the set points or RUN/RESET status.

A Appendices A-2 Troubleshooting Before Requesting Repairs If communications are not functioning properly, check the items in the following table before requesting repairs. If normal operation cannot be restored even after checking everything, return the product to your OMRON representative. Problem: Communications are not possible or communications errors occur. Item The communications wiring is not correct. The communications line has become disconnected. The communications cable is broken.
A Appendices A-4 Item Confirmation Page The host device is detecting the absence of a response as an error after broadcasting a command or sending a software reset command. The host device sent another command before receiving a response from the Controller. The host device sent the next command too soon after receiving a response from the Controller. The communications line became unstable when the Controller’s power was turned ON or interrupted, and the host device read the unstable status as data.
