If different settings are made with the RS-232C auxiliary setting jack and remote I/O communications, the settings made with the RS-232C auxiliary setting jack will last only until the next time the value is refreshed for remote I/O communications. RS-232C Auxiliary Setting Jack and FINS Messages Data written for the RS-232C auxiliary setting jack and FINS message are both achieved using commands If different settings are made with the RS-232C auxiliary setting jack and a FINS message, the last command that was executed will determine the value of the setting. Saving Set Values Any data sent with DeviceNet is automatically saved and will remain in memory even if the power supply is turned OFF. Data set from the RS-232C auxiliary setting jack, however, will not be saved unless the Memory Write Command (WE) is executed before power is turned OFF. 65 SECTION 1 Serial Communications Control This section provides general information on serial communications and communications checks. 1-1 1-2 1-3 1-4 1-5 Communications Control Procedure . . 68 69 69 70 70 67 Communications Control Procedure Section 1-1 1-1 Communications Control Procedure The communications procedure of the E5ZE is a special conversation type. In each E5ZE system, all communications are initiated by the host computer of the system by sending a character string called command block to an E5ZE of the system. The E5ZE then sends a character string called response block back to the host computer, i. e. , each time a block is transmitted, the transmission right is also transferred. Each block begins with a start character, @, and the unit number of the E5ZE and ends with an FCS and a terminator. The E5ZE sends a response block back to the host computer whenever the host computer sends a command block to the E5ZE. The response block is processed by the host computer. @ Unit no. Header code Host system Text FCS Terminator Command block @ Unit no. Header code Text FCS Terminator Command block 4 s max. Header code Text FCS Terminator Response block 20 ms min. Note Command Block: Response Block: A block sent from the host system. (Character string) A block sent from the E5ZE. (Character string) The host computer must be set up to read the responses sent by the E5ZE. [. . . ] The fuzzy scale 1 value of a control point will be automatically adjusted according to the PID constants. The fuzzy scale 1 value can be changed manually after PID constants are set for the bank.
