7.5.28.7 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 da ta transmission
without handshaking)
C1707 C1717 C1727
No handshaking, minimum wiring
Set BCD mode = 0.
Function
• Cyclic reading of BCDs
– No acceptance signal (BCDx-READ), e.g. for reading a BCD decade switch required.
• 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.
