Allen Bradley 1770-KF2 and Yokogawa Model: ACM11 / Style: S2
We have 5 Allen Bradley SLC 5/04 nodes in DH+ connected to DH+ port of 1770-KF2 module.
KF2 module Address is 010 (octal).
SLC node address is 1, 11, 12, 13, and 14.
Yokogawa DCS can see SLC node 1, 11 & 12.
Dip switch settings on the KF2 is as below
1. Half Duplex settings:
Switch 8: RS232
Switch 1: Half duplex, BCC error checking, even parity, and no response.
Switch 2, 3 & 4 (address): 010 (octal)
Switch 5: 57K (DH+ baud rate)
Switch 6: 4,800 (Serial baud rate)
Switch 7: DH+
Statuses of Diagnostic LEDS present in front of the KF2 module are as below:
Power: Green (continuously on)
XMTG: Green (continuously on but blinks every 4 seconds otherwise always steady on)
RCVG: Green (continuously on)
Ready: off all the time but Blinks one time every 4 seconds and after another 4 seconds blinks 4 times continuously and stops then the cycle repeats every 4 seconds interval.
Active: Steady / continuously on and blinks every 4 seconds
CPU: off all the time but blinks every 4 seconds and remains off for another 4 seconds.
Now I connected my laptop com1 port to RS232 port of KF2 module. In Rslinx I selected
“RS232 DF1 devices”.
In the “Configure RS232 Devices” dialog box I entered the below
Com port: com1 (no other device was using COM1 port)
Device: 1770-KF2/1785-KE/Scanport
Baud rate: 4,800
Station no.: 010
Parity: Even
Error Checking: BCC
Stop bits: 1
Protocol: Half Duplex
With the above setting when I pressed auto configure I got the error message to check cable etc.
2. Full Duplex setting:
Now I changed the dip switch settings on the KF2 module to the below
Switch 8: RS232
Switch 1: Full duplex, CRC, None, Yes (response)
Switch 2, 3, and 4 (address): 010 (octal)
Switch 5: 57K DH+ baud rate
Switch 6: 9600 (serial baud rate)
Switch 7: DH+
Also I changed my settings in Rslinx DF1 configuration dialog box to reflect the Full duplex settings. (Com1 , Device: KF2 , Baud rate: 9600, Error checking: CRC, Protocol: Full duplex). Now when I pressed Auto configure. Dialog box showed Auto configure successful.
I can see from RSWHO all the nodes.
How do I see all the nodes with previous setting of half duplex protocol?
Yokogawa DCS ACM11 module supports only half duplex protocol.
Many thanks for all your Feed backs
