Question

Addressing when connect to a device using Open Protocol?

Hi,

 

I am testing a device using the Open Protocol (Torque Ethernet Driver) to connect to KepwareEX for gathering data. I have read the driver help but not sure what to type in the address field. It said the address syntax is ITEMNAME<BIT.INDEX>. For example, if I want to read the data "Last tightening Results" with MID 0061, so the ITEMNAME should be LTR_TORQUE_VALUE, isn't it?

According to the Open Protocol user guide, if I want to use MID 61, revision 1, the torque value is from the byte 141 to byte 146. What should I type in the address tag field on Kepware OPC server?

Could you give me an example?

 

Many thanks,

Hi Tan_Tran,

 

You are correct the address you need is LTR_TORQUE_VALUE, if you want the current Torque value. Are you experiencing any issues using this address?
