• Supported baud‑rate: 9.6 k‑12 Mbps auto‑adaptable
• Maximum slave quantity: 64 DP slave devices
• I/O data buffer: 244 bytes input / 244 bytes output per slave station
• Mechanical form: Single‑slot plug‑in for Series 90‑30 rack; non‑hot‑swappable
• Status indicators: LED indicators for power, network running and diagnostic fault status
• Power consumption: Supplied by PLC backplane 5 VDC
• Operating ambient temperature: 0 ℃ ~ +60 ℃; storage temperature ‑40 ℃ ~ +85 ℃; relative humidity 5‑95 % non‑condensing
• Configuration tool: PROFIBUS configuration software, download bus parameter to module via PLC backplane bus

Core Functions & Features

1. Acts as DP master station, executes cyclic real‑time data exchange with field DP slaves including remote I/O modules, variable‑speed drives and field bus transmitters.
2. Stores slave diagnosis information, reports station failure, communication interruption and slave hardware fault to CPU for system alarm logic.
3. Supports standard PROFIBUS‑DP cyclic communication; bus parameters including baud‑rate, station address and watchdog time can be edited offline.
4. Internal shared RAM exchanges field‑bus data with Series 90‑30 CPU through rack backplane.

On‑site Installation & Commissioning Notes

1. Power off PLC rack completely before inserting or removing HE693PBM101F module, this hardware is non‑hot‑swappable.
2. PROFIBUS‑DP cable shall adopt standard shielded twisted‑pair cable. Install matching termination resistor at two physical ends of bus cable.
3. Complete bus configuration: define slave list, I/O mapping and watchdog time; download configuration to PLC and communication module.
4. Verify CPU firmware version meets requirement; lower‑revision CPU will result in module communication abnormality.
5. After commissioning, check module LED status, confirm all slave stations enter normal data‑exchange status
