[. . . ] H143-E1-01 EJ1G Modular Temperature Controllers for Gradient Temperature Control USER'S MANUAL EJ1G Modular Temperature Controllers for Gradient Temperature Control User's Manual Produced October 2006 iv Preface This manual describes the EJ1G Modular Temperature Controllers for Gradient Temperature Control, including information on functions, performances, and application methods. Observe the following precautions when using an EJ1G Modular Temperature Controllers for Gradient Temperature Control. · 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. [. . . ] The EJ1G clears the Response Bits. PLC processing Clears the Request Bits. EJ1G processing Clears the Response Bits. 1. 2. 109 Programless Communications Operation Procedure Monitor Section 5-6 Once the PLC sets the value of the Read Request Bits, the EJ1G writes the value set under Programless Upload Settings to the PLC memory area. · Single Read The parameters set in the Programless Upload Setting are read once. 3. The EJ1G sets the Read Response Bits.

When the Read Request Bits are set (step 1), steps 2 and 3 performed automatically. · Read Settings With the normal monitor operation, the value set under Programless Upload Setting is read to the upload data area in PLC memory. With the Read Setting operation, the value set under Programless Download Setting is read to the upload data area in PLC memory to confirm that the setting is correct. 3.

The Read Request Bits are cleared by the PLC. XXXX Monitor Values If the monitor value has a decimal point, keep the decimal point in mind when handling the monitor value. Example: monitor value 03E8H or 1000 100. 0 The set value in the EJ1G will not change even if the monitor value is changed. Checking Programless Communications Operation from the PLC To confirm that programless communications are working from the PLC, confirm that reserved bit 15 of the Communications Status under the Programless Download Settings is changing. Bit 15 repeatedly turns ON/OFF during communications. Bit 15 alternates between ON and OFF, changing at each programless communications. Example: Multi Read Each time all the parameters set under Programless Upload Settings are written to the PLC, bit 15 changes between ON and OFF. 112 Programless Communications Setting Changes Section 5-6 To change EJ1G settings from the PLC, first change the values in the Download Area in the PLC memory and then set the Setting Change Request Bits. The EJ1G will then read the Download Area in the PLC memory and change the corresponding settings. [. . . ] There is an error in the group settings.
