What is MPI cable Siemens?
The Multi-Point Interface – Siemens (MPI) is a proprietary interface of the programmable logic controller SIMATIC S7 of the company Siemens. It is used for connecting the stations programming (PC or personal computer), operator consoles, and other devices in the SIMATIC family.
What is MPI and DP?
MPI is a subset of profibus and allows only up to 31 slaves with a fixed communication speed of 187,5 baut. Profibus DP is a protocol for profibus with remote IO and allows up to 126 slaves up to speed of 12Mbp/s.
How do I connect my Siemens PLC to my computer?
Setting up communication between PC and PLC (PPI)
- Connect the PPI cable between your computer and the PLC.
- Open the Communications dialog in STEP 7-Micro/WIN.
- Click on Set PG/PC Interface.
- Select PC/PPI cable (PPI) interface.
- Open the Local Connection tab and choose the port to which the cable is connected.
What is PG PC interface Siemens?
Set PG/PC Interface allows you toconfigure the communication between the PG/PC and the PLC / Drives / HMIs / other Siemens devices. Using this we select the actual communication hardware and the protocol using which various Siemens Softwares will communicate with PLCs and other devices.
What is MPI protocol?
Message Passing Interface (MPI) is a communication protocol for parallel programming. MPI is specifically used to allow applications to run in parallel across a number of separate computers connected by a network.
What is rs485 used for?
RS-485 is an industrial specification that defines the electrical interface and physical layer for point-to-point communication of electrical devices. The RS-485 standard allows for long cabling distances in electrically noisy environments and can support multiple devices on the same bus.
What is the difference between Modbus and Profibus?
Profibus is also a master-slave type protocol like Modbus (see Figure 2) but with an additional token ring protocol to allow for multiple masters. Also, unlike Modbus, all devices go through a startup sequence during which they “join” the network. Each slave maintains a failsafe timer.
How do I download Siemens PLC?
To perform this type of download select the block(s) you wish to download and then select the PLC > Download menu item or the download button . Holding down the Ctrl key or the Shift key allows more then one block to be selected at a time.
What is the time base for a Siemens PLC?
time base is 00 = 10ms.
What does PG PC stand for?
programming device
(1) Your PG is your programming device (the device you use to program / interact with your PLC). In most cases that means a computer with programming software. For example, WinCC, Step 7 or TIA software (in the Siemens family). Hope that clears things up a bit.
How do I install PG PC interface?
In the SIMATIC Manager you open the “Set PG/PC interface…” dialog by going to “Options > Set PG/PC interface…” and select the desired interface in the “Interface parameters used” list.
Why is MPI used?
How to use the Siemens MPI port adapter?
Target Machine Cable / Adapter Comments GP, PS-P, PC/AT(PL), PS-G Cable for Siemens MPI Port Adapter (Pro-face: GP070-MPI-41) – When connecting to a 9pin port on the target machine, use a 9/25 pin adapter. – GP070-MPI-41 cable uses male connections. 4 Siemens Simatic S7-300/400 Series MPI Driver 3 Supported Device Addresses
What are the connectors for MPI and Profibus?
For very short distances (5 m. max) and low speed (187,5 kB on MPI, 1,5 MB on Profibus), we have setup Sub-D 9 pin connectors with straight RS-485 connections: pin 8 to pin 8, pin 3 to pin 3, pin 5 to pin 5. It works, but we can only do a point to point (1 master, 1 slave) conection.
Which is MPI driver does Siemens SIMATIC S7-300 use?
Siemens Simatic S7-300/400 Series MPI Driver Ł This manual explains how to connect the target machine with other manufacturer devices. For information about how to use the Pro-Designer software, please refer to the Pro-Designer Online Help. Ł The types of target machines that are compatible with Pro-Designer depends on the version of Pro-Designer.
Which is the correct MPI address for a PLC?
The Local Node, Target Node, and MPI addresses must be less than or equal to the Highest Node Number. 7 Siemens Simatic S7-300/400 Series MPI Driver 6 I/O Manager Configuration The driver and protocol, which enable communication between the target machine and the PLC, depends on the PLC type.
