L5203 M/Ordinal Writer - RG354537

Description

This block writes a parameter to a Eurotherm Bisync slave device connected to the L5203 module in which the block resides.

In order to execute, the L5203 M/Ordinal Writer must be referenced in the step list of an L5203 M/Sequencer II function block; information is written when the step is performed.

The instrument number (INO) and parameter number (PNO) are specified as configuration parameters in the block.

If an error is encountered, an error code (a bit field, described below) is stored in the function block until read or overwritten by another error.

Parameters

Input	Data to be written.  Expects an ordinal.

Get Error	Returns last error code (see below).

Get Input	Returns an ordinal.

Error Code Bit:

0	(False if a write transaction).

1	Retry count exceeded.

2	Slave refused transaction.

3	Scaling overflowed.

4	Response PNO did not match requested PNO.

5	Bad format number encountered.

6	(Unused).

7	Internal state machine error.

8	Bad or unexpected character received.

9	Transmit buffer overflowed.

10	Receive buffer overflowed.

11	(Receive buffer empty).

12	Character parity error.

13	Character overrun.

14	Character framing error.

15	Break detected and cleared.
