Siemens SIMATIC ET 200S DP Master Interface Module

Description

• 6ES7138-4HA00-0AB0​ → DP Master Interface (for IM 151-7 CPU or IM 151-8 PN/DP CPU in ET 200S rack)​ — Allows an ET 200S station equipped with an IM 151-7 CPU (S7-314 based) or IM 151-8 PN/DP CPU​ to act as a PROFIBUS DP Master​ on a second PROFIBUS network — i.e., the ET 200S CPU can control other DP slaves (drives, other ET 200S/X I/O) via this module plugged into the local rack. Note: This is NOT the IM (Interface Module) that connects ET 200S to a DP Master — it’s an expansion card for the CPU-equipped ET 200S rack to become a DP Master itself.
• 6ES7138-4DA04-0AB0 / 6ES7138-4DF01-0AB0​ → Counter / Trigger / Technology Modules for ET 200S​ — 6ES7138-4DA04-0AB0 = Counter Module (2 channels, 24V, 20 kHz / 100 kHz — depends on version — for pulse counting, frequency measurement); 6ES7138-4DF01-0AB0 = SSI (Synchronous Serial Interface) or similar special function module​ — verify exact function by full 20-char code; 4DF01 is often SSI absolute encoder input module for ET 200S. These plug into ET 200S I/O slots (after IM + PS) and occupy process image areas.

Key Features (6ES7138-4HA00-0AB0 DP Master IF for ET 200S CPU Rack)

• Function: Enables IM 151-7 CPU / IM 151-8 PN/DP CPU based ET 200S rack to operate as PROFIBUS DP-V0/V1 Master on a separate bus
• Max. Slaves: Up to 32 DP slaves (typical — depends on IM 151-7 CPU memory / S7-300 CPU inside IM 151-7)
• Baud Rate: 9.6 kbps … 12 Mbps (PROFIBUS standard)
• Bus Connector: Sub-D 9-pin (standard PROFIBUS)
• Configuration: Via STEP 7 HW Config — insert as “DP Master” in the ET 200S CPU’s DP interface (the 4HA00 appears as a DP port in the CPU’s properties)

Key Features (6ES7138-4DA04-0AB0 Counter Module — ET 200S)

• Channels: 2 (independent)
• Count Frequency: 20 kHz / 100 kHz (depending on exact sub-version — 04 often = 100 kHz for 24V inputs)
• Functions: Counting (up/down), Frequency measurement, Period measurement, Comparison (setpoint reached)
• Input Voltage: 24 V DC (sink/source — typical PNP/NPN both usable with proper wiring)
• Diagnostic LEDs: Per channel

Model & Capability Table (Listed ET 200S 6ES7138-4xx Modules)

⚠️ Critical Fit Notes:

1. 4HA00 ≠ IM (Head Module)!​ The 6ES7138-4HA00-0AB0 is an expansion module that goes in a standard I/O slot of an ET 200S rack that already has an IM 151-7 CPU or IM 151-8 PN/DP CPU (with CPU function). It does NOT replace the IM 151-1 (which is the slave interface to a Master). Do NOT confuse with IM 151-1 (6ES7151-1AA05-0AB0 etc.) which is the standard DP slave interface!
2. Terminal Block (TB) Separate: Like all ET 200S modules, 6ES7138-4HA00 / 4DA04 / 4DF01 snap onto a Terminal Block (TB)​ ordered separately — standard TB: 6ES7193-4CA10-0AA0 (screw); 6ES7193-4CB10-0AA0 (spring). For 4DA04 counter — may want color-coded TB (6ES7193-4CF00-0AA0 = dark gray for counter?). Match TB color if using colored TBs.
3. DP Master IF Usage: In STEP 7 HW Config — with IM 151-7 CPU inserted → go to its DP interface tab → you’ll see option to add “DP Master Interface (4HA00)”. Insert 4HA00 → set DP address / baud / slave config for the 2nd bus. The IM 151-7 CPU must have sufficient work memory for DP Master table.
4. Counter (4DA04) Wiring: Count inputs typically A/B (quadrature) or Up/Down — wire encoder A/B to terminals; reference to 24V/0V per manual. Gate/Control inputs for enable/latch.
5. SSI Module (4DF01): If indeed SSI — clock/data wires from SSI encoder to TB terminals; set bit length (13–25 bit), code (Gray/Binary), direction in HW Config.

Warranty & After-Sales

• Factory new units: 12 months warranty
• Refurbished units: 3-6 months warranty (DP Master IF → link test with slave; Counter → pulse inject & PIW read back in STEP 7 Monitor)
• Technical support for:
  • Correct application check (4HA00 needs IM151-7 CPU or IM151-8 PN/DP CPU version​ — NOT for plain IM151-1 slave-only rack!)
  • Terminal Block selection (standard screw 6ES7193-4CA10-0AA0; color-coded 6ES7193-4CF00-0AA0 for counter; 6ES7193-4CG00-0AA0 for analog etc.)
  • STEP 7 HW Config (insert into IM151-7 CPU rack → DP Master IF → configure 2nd bus slaves; Counter → assign addresses, set count mode/gate)
  • Counter wiring (A/B quadrature from encoder → terminals; gate/reset wiring)
  • Cross-ref to IM 151-7 CPU (6ES7151-7FA02-0AB0) if you need the CPU-equipped head module
