cMT3102X Siemens MPI Commissioning Checklist (S7-300/400/200)

1. Mandatory Preconditions (Communication fails if not met)
2. Port Restriction: Only COM2 and COM3 (RS485 2W) support MPI; only one can be used for MPI, not both. كوم1 (RS232) does not support MPI.
3. Fixed Baud Rate: 187.5Kbps only, 19.2ك / 9.6K not supported
4. إصدار البرنامج: V2 hardware requires EBPro ≥ V6.08.01; older hardware minimum V6.05.02. Select exact model cMT3102X / cMT3102X(V2)
5. COM3 Mode Lock: Once COM3 is set to RS485 MPI, COM3 cannot switch to RS232. MPI function is disabled if COM3 is set to RS232.
6. أسلاك الأجهزة (9-pin D-SUB Con.A, أنثى)

1) Pinout (RS485 2W half-duplex)

كوم2 / COM3 RS485 2W:

Pin1 = Data(ب)

Pin2 = Data+ (أ)

Pin5 = GND (signal ground, must connect to PLC pin5)

2) PLC MPI Male Connector

Pin3 = A(+), Pin8 = B(-), Pin5 = GND

3) Wiring Reference

واجهة المستخدم البشرية: 1-ب, 2-أ, 5-أرض

بلك: 8-ب, 3-أ, 5-أرض

4) Bus Termination Resistor (MPI is simplified Profibus)

Terminate both ends of bus (واجهة المستخدم البشرية + بلك) with 120Ω resistor

Only two end nodes terminated; no termination on middle nodes

Flip the switch to ON on original Siemens MPI connector to activate termination resistor

3. PLC Parameter Setup (Step7 Classic / TIA Portal)
4. Open hardware configuration → CPU properties → MPI interface
5. معدل الباود: 187.5 كيلو بايت في الثانية (مُثَبَّت)
6. عنوان المحطة: 1~31, must differ from HMI address
7. Highest station address: 31; keep default bus parameters
8. Download hardware configuration and restart PLC
9. S7-200 Note: Port0 must be MPI mode, not PPI master mode, otherwise MPI communication fails
10. EBPro Project Configuration Step-by-Step
11. System Parameters → Model

Select exact model: cMT3102X / cMT3102X(V2). Wrong model causes communication failure.

2. Add PLC Device & سائق

Device type: Siemens S7-300/400 MPI (MP300)

واجهة: COM2 or COM3 (choose one only)

Communication mode: RS485 2W (half-duplex)

3. معلمات الاتصال (Match PLC exactly)

معدل الباود: 187500

HMI station address: 0 (مُثَبَّت, do not change)

PLC station address: same as configured in PLC hardware (على سبيل المثال. PLC=2)

نفذ الوقت: default 2000ms, do not set below 1000ms

Highest station address: 31

4. Port Mode Lock (Common Pitfall)

Enter HMI system menu on power-up:

Set COM2/COM3 to RS485 2W, NOT RS485 4W or RS232

Do not activate both COM2 and COM3 serial communication; MPI occupies one port exclusively

5. Address Format (Avoid Read Failures)

مدخل: أنا

الإخراج: س

ذاكرة: م

Data Block DB: DB1.DBW0, DB1.DBD4 (DB block must be created and downloaded to PLC beforehand)

Accessing non-existent DB blocks triggers no response error

5. HMI Local System Setup (Before Download Project)
6. Enter system menu by long-pressing top-left corner on boot; كلمة المرور الافتراضية: 111111
7. Serial port configuration: confirm COM2/COM3 is RS485 2W
8. Disable CODESYS runtime (CODESYS occupies serial port and blocks MPI)
9. Save settings and reboot HMI
10. Step-by-Step Commissioning Workflow

خطوة 1 Hardware continuity test (المتعدد)

1. خارج السلطة: resistance between A and B ≈60Ω (both ends 120Ω termination active)
2. No short circuit between A/B and ground
3. Signal ground connected; common ground to avoid differential voltage and port damage

خطوة 2 Serial loopback test (Verify HMI port health)

Short HMI A and B pins, create free protocol device. If send/receive works, serial hardware is good.

خطوة 3 PC simulation test

1. Run online simulation in EBPro
2. Enable Diagnoser (System Parameters → Remote → Enable Diagnoser) to view real-time packets
3. Transmit packets only, no receive: الأسلاك / station ID / baud rate error
4. No packets sent: wrong port, port occupied by CODESYS, wrong model selected

خطوة 4 Download project to HMI and online test

1. Test MPI alone; disconnect Ethernet and CAN to eliminate interference
2. Keep cable short; MPI total length ≤50m. Use Profibus shielded cable for longer runs
3. Shield single-end grounding: ground only at PLC side; leave HMI shield floating to prevent ground loop
4. الأخطاء الشائعة & الحلول (Device No Response)

عيب 1 HMI shows【Device No Response】

1. Top cause: COM2+COM3 MPI enabled together → use only one port for MPI
2. Baud rate mismatch (PLC 19.2K vs HMI 187.5K) → set both to 187.5K
3. Missing termination resistor, signal attenuation → enable 120Ω at both ends
4. Serial port occupied by CODESYS → stop CODESYS runtime and reboot
5. RS485 4W selected by mistake → switch to 2W half-duplex

عيب 2 Intermittent disconnection, jumping data

1. Shield grounded at both ends → ground shield only at PLC
2. Excessive bus length or T-branches → MPI bus does not allow T taps
3. Different power grounds with voltage difference → share same DC24V supply for HMI and PLC

عيب 3 M area readable, DB blocks cannot be read

1. DB block not downloaded to PLC
2. “Optimized block access” enabled in TIA Portal, non-addressable for HMI

✅ Fix: Uncheck optimized block access, recompile and download PLC program

8. Additional Restrictions
9. cMT3102X does not support MPI + Profibus simultaneously
10. MPI works as master only (HMI master, PLC slave); cannot be MPI slave
11. الأعلى 31 nodes on one MPI bus; HMI station address fixed at 0
12. Quick Check List (On-site tick list)

☑ Port: Only COM2 OR COM3, no dual MPI

☑ Mode: RS485 2W, not 4W or RS232

☑ Baud rate: Strictly 187.5K

☑ Station ID: HMI=0, PLC≠0, unique addresses

☑ Termination: 120Ω enabled at HMI and PLC ends

☑ Cable: Profibus shielded cable, no T-branch, total length＜50m

☑ Software: Correct model, EBPro version compliant, CODESYS disabled

☑ DB block: Optimized access disabled, downloaded to PLC

☑ Common ground, shield grounded only at PLC
