Industrial Ethernet Protocols and Network Integration
The module incorporates a 2-port Industrial Ethernet switch operating at 10/100 Mbps, which allows line-topology network structures without external Ethernet switches. It manages up to 128 S7 communication links and up to 64 open communication connections using standard SEND/RECEIVE blocks.
Verification: Confirm that combined CPU and network connection demands stay within the maximum limit of 128 active communication links.
When functioning as a PROFINET IO Controller, the unit manages up to 128 field devices (including up to 64 IRT devices) with data volumes of up to 1433 bytes for input and output variables per device. Network security and access control are supported through an IP Access Control List (ACL), while Fast Startup and PROFIenergy functions optimize system performance and energy usage.
System Powering and Mechanical Installation
Power is drawn directly from the S7-400 backplane bus at 5 V DC, eliminating the need for an external supply cable to the front panel. The module consumes 1.4 A under normal operation, generating a typical power loss of 7.25 W.
Verification: Ensure the S7-400 power supply module (PS) has sufficient 5 V DC capacity on the backplane bus to accommodate the module's 1.4 A requirement.
The compact single-width casing measures 25 mm wide, 290 mm high, and 210 mm deep, slotting directly into standard S7-400 racks. Operating within standard IP20 control enclosures, it withstands temperatures up to +60 deg C and non-condensing relative humidity up to 95%.
Frequently Asked Questions
Q: Does the 6GK7443-1EX30-0XE0 require an external 24 V DC power connection? A: No, it derives its operational power directly from the S7-400 backplane bus at 5 V DC (drawing typically 1.4 A).
Q: How many PROFINET IO devices can be configured under this communication processor?A: It can act as a PROFINET IO Controller managing up to 128 total IO devices, including up to 64 IRT-capable devices.
Q: Can the integrated Ethernet ports be used to create line topologies? A: Yes, the module features two RJ45 ports backed by an integrated 2-port 10/100 Mbps switch, enabling direct daisy-chain connection to adjacent devices.
