Sorry more one time
All my efforts to communicate TD320 with epl101 fail
I Ń‚ried rs482 and rs232
communication LED lid , but i can't write or read from slave
may be necessary some additional configuration?
I connect TD320 with EPL101 via RS485 EXP_1 address 3 and othe EPL101 via RS232 COM1 address 2
it was checked with 2 different DP320
in this configuration i sometimes see wrong changes in " read 110" position
Can you help me find my mistakes?
this is my configuration:
from PC via RS485 I can rich and change registers in TD320 or EPL101

Hello,
the problem is the index of COM_ and EXP_ command.
The index must be different every COM_ and EXP_ command, the first is COM_1, the second is COM_2 and keep going like this.
The correct file is link to this message.

Thank you.
Everything is work good exept AI inputs.
Can you show me how configure AI1 - AI4 for NTC 10K probe ?
Is it necessary configure MIN, MAX, OFFSET, and GAIN ?
SM40 (2040) - SM43(2043) set to 15 (NTC 10K)
JP2, JP3, JP4 are set, 1,28V on AI1 (NTC 10K probe connect) ; 2,5V AI2-AI4 contacts(open)
I see AI1 - AI4 DISABLE (SM60-SM63 EPL101 PC monitoring)
