[. . . ] H142-E1-03 EJ1 Modular Temperature Controllers USER´S MANUAL EJ1 Modular Temperature Controllers User's Manual Revised July 2008 iv Preface This manual describes the EJ1 Modular Temperature Controllers, including information on functions, performances, and application methods. Observe the following precautions when using an EJ1 Modular Temperature Controller. · Do not allow the Temperature Controller to be handled by anyone except a specialist with sufficient knowledge of electrical systems. · Read this manual thoroughly and be sure you understand it before attempting to use the Temperature Controller and use the Temperature Controller correctly according to the information provided. [. . . ] Communications will not be normal if this setting is too short. Variable type F0/B0 Parameter name Setting range Default 2000 Programless Communications 10 to Receive Wait Time (Common) 10000 ms Adjusting Communications Time with PLC Conditions for use The Programless Communications Protocol cannot be NT Link (1: N). Note Reset the EJ1 to enable the setting. Either continuing or stopping operation can be selected for when errors occur in the programless link. Variable type F0/B0 Parameter name Setting range Default 1 Selection of Programless Communi- 0: Continue cations Operation during Error 1: Stop (Common) Operation for Error in Programless Link V1. 1 Conditions for use No special conditions 134 Programless Communications Note Reset the EJ1 to enable the setting. Setting range 0: Continue Section 5-1 Operation Programless communications will be restarted automatically when the cause of the programless link error has been removed and communications are possible with the PLC. Read/write operations for PLC memory will not be performed even after the cause of the programless link error has been removed and communications are possible with the PLC. Refer to Method for Canceling Communications Errors on page 154 for information on clearing the error. 1: Stop Note When using the default Basic Unit settings, programless communications will stop if a programless link error occurs. This will make reading parameters, changing settings, and executing operation commands impossible. When starting normal operation, it is recommended that the programless communications error operation selection be set to continue operation. PLC Settings SYSMAC CS/CJ Series MELSEC-Q Series The settings are the same as made when checking operation. Refer to Checking Operation with SYSMAC CS/CJ Series PLCs on page 117. Make settings based on the following table if the baud rate or transmission settings need to be changed. Channel CH1 Switch number Bit position Description SW01 b0 to 7 Transmission settings SW02 CH2 SW03 SW04 SW05 b8 to 15 --b0 to 7 b8 to 15 ----Baud rate setting Communications protocol setting Transmission settings Baud rate setting Communications protocol setting Station number setting Common for both CH1 and CH2 Transmission Settings Bit b0 b1 b2 b3 b4 b5 b6 b7 Description Operation setting Data bits (See note. ) Parity bit (See note. ) Even/odd parity (See note. ) Stop bits (See note. ) Checksum Write during RUN Setting modifications OFF (0) ON (1) 0 1 1 1 0 1 1 1 E Setting E Independent Linked 7 8 No Odd 1 No Prohibited Prohibited Yes Even 2 Yes Allowed Allowed Note Change the settings if required. If changes are made, make the same settings on the EJ1. 135 Programless Communications Baud Rate Setting Communications baud rate 9. 6 (kbps) 19. 2 (kbps) 38. 4 (kbps) 57. 6 (kbps) 115. 2 (kbps) (See note. ) Setting (b8 to 15) 05H 07H 09H 0AH 0BH (recommended) Section 5-1 Note If both channel 1 and channel 2 are used on the QJ71C24(-R2), make sure that the total baud rate for both channels is 115. 2 kbps or less. Note Make the same settings on the EJ1. Communications Protocol Setting Communications protocol setting MC Protocol, Format 5 Programless Communications Protocol MC Protocol (format 5) Setting 0005H Note Make sure this setting is the same as the Programless Communications Protocol parameter. Station Number Setting Set to 0000H to match the EJ1 setting. If the station number of the Serial Communications Unit is set to any value except 0, set the programless communications node number in the EJ1 to the same value. MELSEC-QnA/QnAS Series Make the settings shown in the following table for the channels being used. Setting switch Station number switch Mode switch Setting 00 Dedicated protocol Binary mode Format 5 Independent operation 8 bits Enable Even 1 bit Yes Enable Enable 115. 2 kbps (See note. ) Transmission specifications switch Operation setting Data bits Parity bit enable/disable Even parity/odd parity Stop bits Checksum Write during RUN enable/disable Setting change enable/disable Transmission rate Note If both channel 1 and channel 2 are used, make sure that the total baud rate for both channels is 115. 2 kbps or less. Note (a) If settings other than those listed above are made, make the same settings on the EJ1. (b) Refer to the PLC operation manual for details on setting methods. MELSEC-An/AnS/FX3UC Series V1. 1 The settings are the same when confirming operation. Refer to Checking Operation with the MELSEC-An/AnS/FX3UC Series on page 125. 136 Programless Communications Section 5-1 5-1-4 Description of Operation Set values are read and changed and operation commands are executed by setting a value in a Request Bits allocated in a PLC memory area.

Continuously reads the parameters set in the Programless Upload Setting Area. Reads the parameters set in the Programless Download Setting Area and writes them to the upload area. Reads the parameters set in the Programless Download Setting Area V1. 1 and writes them to the download area. Changes all of the parameters set in the Programless Download Setting. The first time, all of the parameters set in the Programless Download Setting are changed. Afterwards, changes are made only to parameters for which values have been changed. The first time, the operation command set in the Operation Command Code is executed. [. . . ] Backup RAM = EEPROM RAM write RAM EEPROM Write mode can be confirmed.
