Citect Scada Modent Bit Read

1 post in this topic

Hi team;

I am struggling with a Citect SCADA read of some data. The system is using the "Modnet3" driver over TCP/IP to talk with a system (Modnet 3 as its TCP/IP with first register at 0 and 0 to 15 bits). I am reading the modbus data into variables which is working fine for the analogue values all defined as real in citect.

The Issue I have is that the driver help says I can direct reference a bit in a word, in my case address 45052.1 Holding register 45052 and Bit 1. If I read this as a UINT I get a value of 147 corresponding to bits 1,2,5 and 8.

Citect generates no errors for the tag setup where I define 45052.0 through 45052.15 but all remain as zero in tag lists. 

Any help would be fantastic

Kindest Regards

Howard
