I recognize ongoing support of IsaGraf based ScadaPack 300-series Modbus RTUs is lower priority than new products/features, but the inability to embed source code onto RTUs for upload later in Workbench 6 is a real bummer, and a deal breaker for many of my end users who I'm still supporting in IsaGraf workbench 3.55 and WinXP 32-bit VMWare images.
Please consider restoring the ability to embed/upload source code on the older hardware.
