A Multimedia Card slot accepts memory cards up to 128 MB. The operator panel supports PROFINET IO and connection to SIMATIC S7-1200, S7-200, and S7-300/400 systems through the documented protocols. Its internal software clock can be synchronized; this version has no battery-backed real-time clock. Configuration functions are available for messages, recipes, and process screens. Siemens specifies up to 2.048 variables per device, 500 configurable screens, and 300 recipes. The mounting position is vertical.
