Setting up a AB/DF1 PLC with Pass-Thru for local HMI display
Suppose a simple AB PLC has a single serial port already attached to a
local Human Machine Interface (HMI). Using the DigiOne IAP Pass-Thru
port, we can network enable the PLC and still have our local HMI. This
configuration defines two message sources (the AB/Ethernet or CSP
protocol and the second serial port), one message destination (serial port
1), and the destination table that forwards all messages to serial port 1.
Because RSLinx doesn’t support setting the DST byte in DF1 or CSP, you
will not be able to access two PLCs by one Digi device.
#> set ports ra=1-2 dev=ia
#> set ia master=1 protocol=abethernet active=on
#> set ia serial=1 protocol=df1fd type=master
#> set ia serial=2 protocol=df1fd type=master
#> set ia table=1 addroute=1 active=on protaddr=0-255
#> set ia table=1 route=1 type=serial port=1 protocol=df1fd
Enabling outgoing MSG blocks in above AB PLC
Because DigiOne IAP now supports bi-direction messaging with
DF1 Full-Duplex, the PLC can be enabled to use MSG blocks to query
remote AB/CSP PLC such as PLC5E, SLC5/05, or more DigiOne IAP
devices. Since "route=2" has "ip=0.0.0.0," this means DigiOne IAP will use
its own IP address and the slave address to construct an IP address. So if
the DigiOne IAP’s IP address is 192.168.1.37 and the DF1 DST byte is 7,
then a remote CSP slave at IP address 192.168.1.7 will be accessed.
