Siemens 6ES7441-1AA05-0AE0 SIMATIC S7-400 CP 441-1 1-Channel Point-to-Point Comm Module

The Siemens 6ES7441-1AA05-0AE0 is a SIMATIC S7-400 CP 441-1 coupling module for point-to-point connections, with 1 variable interface configurable as 20 mA TTY, RS 422/485, or RS 232 at up to 115.2 kbit/s. It supports the 3964(R), ASCII, and printer protocol drivers, including direct output to HP-Deskjet, HP-Laserjet, and IBM-Proprinter devices.

Selection Notes

The CP 441-1 interface is variable rather than fixed, so the same module serves TTY, RS 422/485, or RS 232 links depending on which interface module is fitted, instead of committing to one electrical standard at order time. The built-in printer protocol driver removes the need for a separate print-formatting program when the point-to-point link feeds a report printer rather than another controller. For a second independent serial channel on one module, a 2-channel coupling module in the same family is the better fit.

Applications

The variable interface and 3964(R)/ASCII/printer protocol support cover point-to-point links to third-party serial controllers, barcode scanners, and report printers from an S7-400 rack, wherever the field device predates PROFIBUS or Ethernet connectivity.
