Signal Source Note
Name Type DIS DIS format CFG List
BCD3−DATA1 d C1729/2 bin C1728/2 2 Data input (LSB)
BCD3−DATA2 d C1729/3 bin C1728/3 2 Data input
BCD3−DATA3 d C1729/4 bin C1728/4 2 Data input
BCD4−DATA4 d C1729/5 bin C1728/5 2 Data input (MSB)
BCD3−READ d C1729/1 bin C1728/1 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.
BCD3−LOAD d C1729/6 bin C1728/6 2 LOW−HIGH edge = Write data to the code.
BCD3−BUSY−IN d C1729/7 bin C1728/7 2 Generating a collective busy signal
BCD3−FAIL−IN d C1729/8 bin C1728/8 2 Generating a collective fail signal
BCD3−SIGN d − − − − HIGH = Read sign.
BCD3−SEL1 d − − − − HIGH = Read 1st BCD.
BCD3−SEL2 d − − − − HIGH = Read 2nd BCD.
BCD3−SEL3 d − − − − HIGH = Read 3rd BCD.
BCD3−SEL4 d − − − − HIGH = Read 4th BCD.
BCD3−SEL5 d − − − − HIGH = Read 5th BCD.
BCD3−SEL6 d − − − − HIGH = Read 6th BCD.
BCD3−SEL7 d − − − − HIGH = Read 7th BCD.
BCD3−SEL8 d − − − − HIGH = Read 8th BCD.
BCD3−NEW−DATA d − − − − HIGH = BCD accepted, transmit next BCD.
BCD3−EOT d − − − − HIGH = all BCDs read or "CANCEL" recognised.
BCD3−DATA−FLT d − − − − HIGH = BCD code (see chapter 3.5.12.1).
BCD3−BUSY d − − − − HIGH = Data are being transmitted to code.
BCD3−FAIL d − − − − HIGH = Data transmission to code is faulty.
