by the addition of a serial data communication option which allows addressing and reprogramming via a computer terminal or host computer. The RS422/485 communication standard is used with the following logic levels: a) for logic ‘1’ (MARK condition or IDLE state) the ‘A’ terminal of the transmitter is negative (0V) with respect to the ‘B’ terminal (+5V) b) for logic ‘0’ (SPACE cond ...

Operating Instructions (IM/C300). The maximum serial data transmission line length for both RS422 and RS485 systems is 1200m. 3.1 Serial Communication Adaptors for Personal Computers An RS422/485 communications adaptor board is required for serial links. It is strongly recommended that the card used has galvanic isolation to protect the computer from lightning damage and increase immunity from noise ...

1976-2.5-A4 and is used for master (host computer) to slave (C300 Controller) systems. This is the recommended protocol for use with supervisory systems such as ABB Kent-Taylor PC30. The Protocol is: Start transmission (STX) – Command – Identification … End transmission (ETX) – see Figs. 8.1 to 8.6 on pages 7 and 8. Transmission of commands and processing of the subsequent replies must be inc ...

7 PROGRAMMING The general programming procedure is as detailed in the Operating Instructions (IM/C300) but with an additional Serial Data page between the Retransmission Output and Scale Adjustment pages – see Fig. 7.1. Page Header – Serial Page. Transmission Rate Select the retransmission rate required (1200 slowest, 9600 fastest). Controller Identification Assign the controller an identification number (01 to 99) ...

The commands from the master are coded as single characters as follows: R – ‘Read’ (read parameters) M – ‘Multiple Read’ (read a selection of parameters) W – ‘Write’ (write new parameter values). 8.1.1 Mnemonics Each mnemonic for the C300 Controller parameters comprises two characters – see Section 8.6. 8.1.2 Relay Logic Equation (Q1, Q2) The alarm relay assignment is transmi ...
