configuration edits require BNC Host Protocol over Ethernet links.How should we handle protocol timeout settings on our master PLC during commissioning?Set your PLC polling timeouts above 1 second because the module updates its entire register map every 1000 milliseconds.Technical Documentation AccessGet immediate access to product manuals and installation guides:Review the Modbus register map document before mapping your PLC database variables.Download the mounting instructions to clarify rear chassis space tolerances.Access the maritime type-approval certificates to fulfill site engineering file compliance.For urgent engineering assistance, call our support line at 86 158 8020 0923.Copyright © 2026 Oiltech Controls Limited.
