It configures via STEP 7 using its own parameter assignment forms. The module supports a variety of integrated protocol drivers including 3964(R), ASCII, and printer protocols. It does not support RK512 or reloadable customer-specific drivers. The memory required in the S7-CPU memory card ranges from 1–5 KB for parameters and up to 55 KB for message texts, making it efficient for systems with limited memory.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing the Siemens 6ES7441-1AA04-0AE0, verify that your S7-400 rack has a free slot and that your backplane bus can supply the required current (600 mA max from 5 V). Ensure the interface module (TTY, RS232, or RS422\/485) is selected to match your existing peripherals.
