Process Control Bus Integration Characteristics
The ALE111-S00 interfaces directly with the CENTUM VP and CENTUM CS 3000 backplane bus, supporting deterministic data exchange with FA-M3, Modbus, MELSEC, YFGW, DARWIN/DAQSTATION, and PLC-5/SLC500 subsystems. Channel isolation is maintained through independent electrical segmentation per port, preventing cross-bus interference. Cold junction compensation is not applicable to this module; signal integrity relies solely on controlled impedance cabling and termination matching.
Frequently Asked Questions
Q: Is hot-swap supported during live operation?
A: Hot-swap replacement is possible only when installed in a redundant pair configuration within the FCS base unit. Single-module installations require system shutdown before removal.
Q: What is the maximum number of simultaneous connections?
A: The module supports one active Ethernet link per port; concurrent sessions depend entirely on the connected host device’s protocol handling capacity.
Q: Does the module support auto-negotiation for transmission speed?
A: No. The ALE111-S00 operates strictly at 10 Mbps half-duplex as defined by IEEE 802.3 10BASE-T specifications.
Field Installation Guidelines
Mount the module into the designated slot of a compatible Yokogawa base unit ensuring full mechanical engagement. Use only 100 ohm unshielded twisted-pair cabling with proper RJ-45 termination. Maintain cable length under 100 m to prevent signal attenuation. Ensure shield drain wires are grounded at the control cabinet earth bar, not at the module connector. Verify backplane power supply capacity before insertion to avoid overcurrent conditions.
