EDSVS9332P−EXT DE 2.0

3.5.12.7 BCD mode

The BCD mode defines the type of BCD transmission (not the transmission to the target code).

Overview of the settings in the BCD mode:

Function BCD1 BCD2 BCD3

BCD mode

· 0 = no handshaking

· 1 = handshaking

C1706 C1716 C1726

BCD delay in ms (only for data transmission

without handshaking)

C1707 C1717 C1727

No handshaking, minimum wiring

Set BCD mode = 0.

Function

l Cyclic reading of BCDs

– No acceptance signal (BCDx−READ), e.g. for reading a BCD decade switch required.

l Set BCD delay (see table)

– Defines the period between reading the individual BCDs. The setting may be necessary if a

bus system provides the data transfer between the BCD decade switch and the FB BCDx

(e.g. terminal extension via system bus).

– The bus system used, the baud rate, and the bus load determine the time to be set.

The BCDs are read in the following sequence:

1. Sign

2. BCD 1

3. BCD 2

4. etc.
