Normally the host computer issues acommand to a PC, and the PC automatically sends back a response. Thus thecommunications are carried out without the PCs being actively involved.
ThePCs also have the ability to initiate data transmissions when direct involvementis necessary.In general, there are two means for implementing Host Link communications.One is based on C-mode commands, and the other on FINS (CV-mode) commands. The SRM1(-V2) supports C-mode commands only. For details on HostLink communications, refer to 4-5 Host Link Commands.PC Setup SettingsWordThe SRM1(-V2)’s peripheral port and RS-232C port settings must be set properly in order to use the Host Link communications, as shown in the following table.BitFunctionSettingPeripheral Port SettingsThe following settings are effective after transfer to the PC.DM 665000 to 03 Port settings0: Standard (1 start bit, 7-bit data, 2 stop bits, even parity, 9,600 bps)1: Settings in DM 6651To matchhost parameters(Other settings will cause a non-fatal error, the default setting (0) will be used, andAR 1302 will turn ON.)04 to 0708 to 1112 to 15Not used.Not used.Communications mode0: Host Link; 1: No-protocol(Other settings will cause a non-fatal error, the default setting (0) will be used, andAR 1302 will turn ON.)242000: HostLinkSectionSRM1(-V2) Communications FunctionsWordDM 6651BitFunction00 to 07Baud rate00: 1.2K, 01: 2.4K, 02: 4.8K, 03: 9.6K, 04: 19.2K08 to 15Frame formatStart00:1 bit01:1 bit02:1 bit03:1 bit04:1 bit05:1 bit06:1 bit07:1 bit08:1 bit09:1 bit10:1 bit11:1 bitLength7 bits7 bits7 bits7 bits7 bits7 bits8 bits8 bits8 bits8 bits8 bits8 bitsStop1 bit1 bit1 bit2 bit2 bit2 bit1 bit1 bit1 bit2 bit2 bit2 bit4-4SettingTo matchhost parametersParityEvenOddNoneEvenOddNoneEvenOddNoneEvenOddNoneTo matchhost parameters(Other settings will cause a non-fatal error, the default setting (00) will be used, andAR 1302 will turn ON.)DM 665200 to 15Transmission delay (Host Link)0000 to 9999 (BCD): Set in units of 10 ms.(Other settings will cause a non-fatal error, the default setting (0000) will be used,and AR 1302 will turn ON.)DM 665300 to 0708 to 11DM 6654Node number (Host Link)00 to 31 (BCD)To matchhost parameters00 to 31(Other settings will cause a non-fatal error, the default setting (0000) will be used,and AR 1302 will turn ON.)Start code enable (RS-232C, effective when bits 12 to 15 of DM 6650 are set to 1.)0: Disable1: SetAny12 to 15End code enable (RS-232C, effective when bits 12 to 15 of DM 6650 are set to 1.)0: Disable (number of bytes received)1: Set (specified end code)2: CR, LFAny00 to 07Start code (effective when bits 08 to 11 of DM6650 are set to 1.)00: 256 bytes01 to FF: 1 to 255 bytesAny08 to 15End code (no-protocol)AnyWhen bits 12 to 15 of DM6653 are set to 0:00: 256 bytes01 to FF: 1 to 255 bytesWhen bits 12 to 15 of DM6653 are set to 1:Setting: 00 to FF (Hex)Note If an out-of-range value is set, the following communications conditions will result.
