I need the drivers to integrate 31 Danload 6000 (Preset), 17 Old Style Danreader Unit from Daniel Ind. We are using a Honeywell SCAN3000 as SCADA with a software developed in C language to integrate the devices (they use a modification of modbus rs485 for the first and current loop for second devices) but we need to increase the quantity of devices to this integration and this makes the software be unstable. We don't like Proprietary Software because they are closed to implement customized modification and they are very expensive. That we like is the drivers to integrate this devices to standard SCADA systems (SCAN3000 or other similars) with all the compatibility that this equipments required. Thanks for the information and your experiences.
