Variable Interface Physics and Protocol Handling

Unit weight is approximately 720 g with an interface module at approximately 100 g, dimensions of 25 mm width, 290 mm height, and 210 mm depth. The CP 441-1 accepts interchangeable interface modules for 20 mA (TTY), RS 232C (V.24), and RS 422/485 (X.27) physics. Shielded cable lengths are limited to 1000 m for TTY, 10 m for RS 232, and 1200 m for RS 422/485. Transmission rate reaches 38.4 kbit/s on RS 422/485 and RS 232, and 19.2 kbit/s on TTY across 3964 (R), ASCII, and printer drivers. Supported printers include HP-Deskjet, HP-Laserjet, IBM-Proprinter, and user-defined models. The module supports 8 connections overall with S7 extended communication. Backplane bus current draw is 700 mA maximum at 5 VDC without an interface module; interface modules draw up to 300 mA at 5 V and 45 mA at 24 V. Parameter memory requirements on the S7-CPU memory card are 1 to 5 kbyte for parameters and 0 to 55 kbyte for message texts. Configuration uses STEP 7 with dedicated parameter assignment forms. A configuration package is included on CD.

Frequently Asked Questions

Q: What is the weight and physical size of the 6ES7441-1AA03-0AE0?
A: Approximately 720 g, with dimensions of 25 mm width, 290 mm height, and 210 mm depth. The interface module weighs approximately 100 g.

Q: What interface physics does the CP 441-1 support?
A: Interchangeable interface modules for 20 mA (TTY), RS 232C (V.24), and RS 422/485 (X.27).

Q: What is the maximum cable length for each interface type?
A: 1000 m for TTY, 10 m for RS 232, and 1200 m for RS 422/485, all with shielded cable.

Field Installation Guidelines

Insert the module into the S7-400 rack and secure the mounting screws. Install the required interface module before energizing. Verify 5 VDC and 24 VDC supply availability. Route shielded cable within the limits of the installed interface physics: 1000 m for TTY, 10 m for RS 232, and 1200 m for RS 422/485. Ground the shield at one end. Confirm the protocol and printer driver configuration in STEP 7 matches the connected device before commissioning. Verify the S7-CPU memory card has capacity for up to 55 kbyte of message texts. Install the configuration package from CD before parameter assignment.
