Source Note
Name Type DIS DIS format CFG List
BCD1−DATA1 d C1709/2 bin C1708/2 2 Data input (LSB)
BCD1−DATA2 d C1709/3 bin C1708/3 2 Data input
BCD1−DATA3 d C1709/4 bin C1708/4 2 Data input
BCD1−DATA4 d C1709/5 bin C1708/5 2 Data input (MSB).
BCD1−READ d C1709/1 bin C1708/1 2 Only required for handshake mode:
· Signal must be applied at the controller for at least
2 ms.
· LOW−HIGH edge starts the data transmission for a
BCD.
BCD1−LOAD d C1709/6 bin C1708/6 2 LOW−HIGH edge = Write data to the code.
BCD1−BUSY−IN d C1709/7 bin C1708/7 2 Generating a collective busy signal
BCD1−FAIL−IN d C1709/8 bin C1708/8 2 Generating a collective fail signal
BCD1−SIGN d − − − − HIGH = Read sign.
BCD1−SEL1 d − − − − HIGH = Read 1st BCD.
BCD1−SEL2 d − − − − HIGH = Read 2nd BCD.
BCD1−SEL3 d − − − − HIGH = Read 3rd BCD.
BCD1−SEL4 d − − − − HIGH = Read 4th BCD.
BCD1−SEL5 d − − − − HIGH = Read 5th BCD.
BCD1−SEL6 d − − − − HIGH = Read 6th BCD.
BCD1−SEL7 d − − − − HIGH = Read 7th BCD.
BCD1−SEL8 d − − − − HIGH = Read 8th BCD.
BCD1−NEW−DATA d − − − − HIGH = BCD accepted, transmit next BCD.
BCD1−EOT d − − − − HIGH = all BCDs read or "CANCEL" recognised.
BCD1−DATA−FLT d − − − − HIGH = BCD code (see chapter 3.5.12.1).
BCD1−BUSY d − − − − HIGH = Data are being transmitted to code.
BCD1−FAIL d − − − − HIGH = Data transmission to code is faulty.
