I have a PLC5/25 connected with 1771-ASB ser B module on Remote I/O port. I am unable to communicate with PLC 5/25 and 1771-ASB module. Both LEDs Active and Fault are blinking at once on 1771-ASB module (it indicates that u should check DIP switch setting). I have connected my PC to PLC 5/25 by 1784-KTX card through DH+ link on programming port (3 pin DH+ port).
Regarding DIP switches I have the following questions:
1- SW1 switch8= should be set on Adapter (ON) or scanner (OFF). When Adapter mode is selected and when scanner mode is selected, should I use Adapter mode or scanner mode for communicating b/w 1771-AB and PLC5/25?
2- On my Processor (5/25) it is given that on
SW2 switch 1 = OFF (for 57.6Kbs baud rate),
in manual it is given an unused bit.
3- Should I close SW3 swtich 1 =ON (end of Remote I/O node?
Shoud I close SW3 switch 2= ON (End of DH+ node?
4- Remember I am using 1/2 slot addressing with 32 bits modules. I have 16 slots in my local chassis. So my PLC chassis will occupy rack 0, rack 1, rack 2 and rack 3.
5- So what address do I put on rack number in SW2 (switch 4-8)?
What address do I put on 1771-ASB SW1 (switch 1-6)?
6- What should I select on SW2 switch 2 (half or full) PLC 5/25 processor?
