ASCII COMMUNICATIONS

The Plastics Controller may be equipped with a two-wire RS485-compatible serial

communications facility, by which means communication may occur between

the Controller and a master device (e.g. a computer or terminal).

5.1

COMMUNICATIONS WRITE ENABLE/DISABLE

When Communication Writes are enabled (in Set Up Mode - see Subsection

3.2.39), the Controller parameters may be adjusted by the master device via the

serial communications link. If communications Writes are disabled, the Controller

will not adjust or change any parameters in response to commands received from 

the master device and will send a negative acknowledgement in response to

such commands. Whether communications Writes are enabled or disabled, the

Controller will return the requested information in response to a Type 2

Interrogation message (see Subsection 5.2.5) from the master device.

5.2

PHYSICAL REQUIREMENTS

5.2.1 Character Transmission

Data format is fixed to be even parity, one start bit, seven data bits and one stop

bit. The Baud rate may be selected to be 1200, 2400, 4800 (default) or 9600

Baud.

5.2.2 Line  Turn-Round

The communications link is operated as a multi-drop half duplex system. When a

device is transmitting, it drives the transmission lines to the appropriate levels;

when it is not transmitting, its outputs are set to a high impedance in order that

another device can transmit. It is important that a transmitter releases the

transmission lines before another device starts transmission. This imposes the

following restraints on the master device:

(a) The transmitter must release the transmission lines within 6ms of

the end of the last character of a message being transmitted. Note

that delays due to buffers such as those used in universal

asynchronous receivers/trans-mitters (UARTs) within the master device

must be taken into account.

(b) The transmitter must not start transmission until 6ms has elapsed

since the reception of the last character of a message.

All Plastics Controllers having an RS485 communications facility adhere to this

standard; thus, provided that the master device conforms similarly to the

standard, there should be no line contention problems.
