DirectSOFT5 Minimum System Specifications
The chart below shows the minimum system configuration and recommended system configuration for a computer with DirectSOFT5. As with any Windows application, a faster processor, more RAM, etc. will definitely improve the performance. While you can definitely run the software on PCs with less capability, you run the risk of resource bottlenecks that can cause serious performance problems and in some cases, even system crashes. DirectSOFT5 is perfectly suitable for use on laptop computers provided they meet the requirements stated below. If your laptop has a built-in serial port, you can use that to connect directly to the DirectLOGIC PLCs. If your laptop does NOT have a serial port, but does have a USB port, you'll need to use a USB-to-Serial adapter to connect to the DirectLOGIC PLCs. If your laptop has an Ethernet port and you're considering a DL05, DL06, DL205 or DL405 system, you should consider using the appropriate ECOM100 to connect to the DirectLOGIC PLCs. Fast CPUs and RAM are cheap. Engineering time and system downtime aren't. Plan accordingly!
