12 Link DUST2 11 Link DUST2 Printing message texts from a message sequencing system requires printers to be connected to SIMADYN D that have a serial communications protocol X--ON / X--OFF with additional telegram protection block (ETX / ACK). 11.1 Hardware Structure 1) All processor boards with configurable serial interface; interface module SS1 (20mA). The cable SC56 is available for connecting the printer to a SIMADYN D processor module. SS2 (V24) and SS3 (RS485) are not permitted ! 2) Communications board CS7 with interface module SS4. The cable SC56 can also be utilized for connection to the communications processor CS7 with SS4 interface module, when the corresponding adaptor is used. This adaptor converts from a 25 pin high density connector to a 25 pin Sub--D socket. The printer must be equipped with the correct interface board and have parameters adapted to the settings (i.e. baud rate, parity) configured in SIMADYN D. Review User Manual: The Printer DR 215-- N (Review Catalog IC40 from AUT and SIMADYN D Update 94/14) is to be used as a message printer. 11.2 Configuring 11.2.1 DUST2 Addresses The DUST2 protocol operates according to the ‘‘Peer to Peer’’principle and therefore can only service a message printer as the communications partner. The output of messages therefore does not require a transmit address (for the CS7/SS4 application, specify a channel name at the corresponding output block; address stage 1 and 2 can be omitted). 11.2.2 Central Block Two central blocks are available for configuring the DUST2 link and for setting the formats for the printer output: -- @DU2 For Serial Links via Processor Module -- @CSD02 For Links via CS7/SS4 Siemens AG 465 980.7107.22 SIMADYN D Configuring Manual Communication Release 02.96 12--1 12 Link DUST2 The DUST2 central block is responsible for the initialization of the communication interface (hardware driver and DUST2 software). In addition, it offers the possibility of a minimum protocol set-up using the connectors: PAR B1 --: Parity Set-Up: Defines the parity in the telegram character (0 = even or 1 = odd number of ones). FRM B1 --: Format Selection: An optical improvement of the text output can be selected between a standard format (FRM = 0) (left-hand and right-hand edge, small font, page break) or an unformatted output (FRM = 1). The format instruction is transmitted by the DUST2 only in connection with the 20mA interface and always after detecting a break: -- SIMADYN is Powered Up; (Current source 20mA from SIMADYN D is active as transmitter) -- Printer is Powered Down: (Current source 20mA from the Printer as transmitter is inactive) -- 20mA Connection Cable SIMADYN<-->Printer is not installed. 11.2.2.1 DUST2 via the Processor Interface The central block @DU2 is available to be configured for the DUST2 link. The block has the task of installing and reporting the data interface to a processor board serial interface. It must be configured on the processor board whose serial interface it is to utilize. The block possesses various initialization connectors, for parameter setting and initialization purposes, with the aid of which it is possible to modify the parameter set-up of the DUST2 even on-line. The block connector QTS indicates successful completion of the link initialization. 11.2.2.2 DUST2 via CS7/SS4 The central block @CSD02 is available to be configured for the DUST2 via an SS4 module on a CS7 board. This block is given the task of initializing and setting the parameters of the data interface on an SS4 module on a CS7 board. All processor modules can access the CS7 board. The data interface to the DUST2 communication via CS7/SS4 is 16 K byte. 11.2.3 Text Output Block Text outputs to a printer in the P16 environment requires the message output block MSC1 to be configured (review chapter ‘‘Message System’’). It only operates in the transmit mode of operation ‘‘Non Overwrite’’, which is the default setting. The MSC1 can be configured in both the permanent FP or interrupt FP. Interconnection Versions for MSC1: The following shows various interconnection versions for the protocol output, by which the message is immediately deleted after it is read. Version 1 : EN=1, IMF=1, IML=0, IMP=0, IMN=0, IMO=1, IME=1 Version 2 : EN=1, IMF=1, IML=0, IMP=0, IMN=0, IMO=1, IME=QMF Version 3 : EN=1, IMF=0, IML=0, IMP=1, IMN=0, IMO=1, IME=QMF Version 4 : EN=1, IMF=QMA, IML=0, IMP=0, IMN=0, IMO=QMA, IME=QMA Version 5 : EN=1, IMF=0, IML=0, IMP=0, IMN=1, IMO=1, IME=1 etc. 12--2 Release 02.96 Siemens AG 465 980.7107.22 SIMADYN D Configuring Manual Communication 12 Link DUST2 Description: The MSC1 always reads the oldest message, sets its binary output QMF=1 (read ‘‘Oldest Message’’), outputs the message (inserts the message into the transmit telegram to the printer) and deletes this message from the message buffer. The transmission subsequently takes place. If the last message has been read from the message buffer, then the ‘‘Oldest Message’’is equal to the ‘‘Newest Message’’and QMF=QML=1. Interconnection example for the protocol output with common message delete when all messages have been read: EN=1, IMF=0, IML=0, IMP=0, IMN=1, IMO=1, IME=QML Description: The MSC1 starts at the very first read of the oldest message and sets its binary output QMF=1 (read ‘‘Oldest Message’’). It then continues to read the next messages until the connector IMN remains at 1. It sets the binary connector QML=1 (read ‘‘Newest Message’’), when it reaches the last ‘‘Newest Message’’. When IME = QML then the complete message buffer is automatically deleted after the message output. Utilize the message output block MSI2 for P32 (review chapter ‘‘Message System’’).
