Hi,
I did try to connect 4 units of EI-1050 in T7. The configuration are as follows: -
1. GND (4 black color cable are joint together and mounted in gnd terminal)
2. FIO0 (4 green color cable - data line are joint together and mounted in FIO0 terminal, set to Output high
3. FIO1 (4 white color cable - clock line are joint together and mounted in FIO1 terminal, set to Output high
4. FIO2 (4 red color cable - power line are joint together and mounted in FIO2 terminal, set to Output high
5. FIO3 (1 brown color cable are mounted in FIO3, terminal are set to Output low)
6. FIO4 (1 brown color cable are mounted in FIO3, terminal are set to Output low)
7. FIO5 (1 brown color cable are mounted in FIO3, terminal are set to Output low)
8. FIO6 (1 brown color cable are mounted in FIO3, terminal are set to Output low)
I did hook up 4 probes and trying Enable FIO3 to Output high and read the data and set back to Output low. Unsuccessful !!!
Please do advice.

Try it first with just 1 probe connected. If that works try 2 probes. Let us know what happens.
Hi, Sorry for my silence.
Upon trying single probe it's giving the reading from any port from FI03 ~FI06. While trying with 2 probes, error prompt.
So it works with 1 probe, but you get errors when you go to 2 probes. Please list the connections you are using for 2 probes.
Hi,
Connection for two probes on EI-1050 in T7. The configuration are as follows: -
1. GND (2 black color cable are joint together and mounted in gnd terminal)
2. FIO0 (2 green color cable - data line are joint together and mounted in FIO0 terminal, set to Output high
3. FIO1 (2 white color cable - clock line are joint together and mounted in FIO1 terminal, set to Output high
4. FIO2 (2 red color cable - power line are joint together and mounted in FIO2 terminal, set to Output high
5. FIO3 (1 brown color cable are mounted in FIO3, terminal are set to Output low)
6. FIO4 (1 brown color cable are mounted in FIO3, terminal are set to Output low)
Please do advice.
For 6, make sure the brown cable for the other probe is connected to FIO4 (it mentions the brown cable is mounted in FIO3). Also, double check all other connections are secure.
I tested with 2 EI-1050s with the same T7 connections as you (using enables lines FIO3 and FIO4 for the two different probes) and am not seeing errors. Try the following register writes and reads for configuration and readings, and see if it helps:
Writes (Configuration):
SBUS_ALL_DATA_DIONUM = 0
SBUS_ALL_CLOCK_DIONUM = 1
SBUS_ALL_POWER_DIONUM = 2
FIO3 = 0
FIO4 = 0
Reads (Readings):
SBUS3_TEMP
SBUS3_RH
SBUS4_TEMP
SBUS4_RH
If that doesn't help, what does your EI-1050 (SBUS) code look, what call is getting an error and what is the error number/message?
Hi,
Thank you for your support, its working in order now. I am using Indusoft SCADA. After setup accordingly as per your request, I am able to activate either one device or both device.
Thank you once again.
