Simatic S7-1500 Advanced Controllers - can they significantly increase the performance of your machines?

The Siemens SIMATIC S7-1500 can significantly increases machine performance with a fast backplane bus, PROFINET interface, and shortest reaction times. SIMATIC S7-1500 has a modular design and that is why it can be scaled in terms of its functionality, so you can adapt and adjust assemblies and functions that will suit your machine design.

The Siemens CPU’s have very large program and data memory in the S7-1500 controller product range for demanding and complex applications with high requirements regarding program scope, performance and networking. Extremely high processing speed for binary and floating-point arithmetic that will significantly increase performance of build machines specially for cross-industry automation tasks in series machines, special machines and plant construction. Its integrated Motion Control functionalities for controlling speed-controlled and positioning axes and support for external encoders makes integrating and process control fast and intuitive.  We can state as example ordering codes:

- 6ES7518-4AP00-0AB0 (SIMATIC S7-1500, CPU 1518-4 PN/DP, Central processing unit with work memory 4 MB for program and 20 MB for data, 1st interface: PROFINET IRT with 2-port switch, 2nd interface: PROFINET RT, 3rd interface: Ethernet, 4th interface: PROFIBUS, 1 ns bit-performance, SIMATIC Memory Card is required)

- 6ES7954-8LT03-0AA0 (SIMATIC S7, memory cards for S7-1x 00 CPU, 3, 3V Flash, 32 GB) for very fast performance and quite bit storage space.

Additionally, we can propose such product as Siemens 6ES7954-8LP02-0AA0 (for fast performance and storage space of 2 GB) and we can also recommend not so expensive CPU with ordering code 6ES7513-1AL02-0AB0 (SIMATIC S7-1500, CPU 1513-1 PN, central processing unit with working memory 300 KB for program and 1.5 MB for data, 1. interface: PROFINET IRT with 2 port switch, 40 NS bit-performance), SIMATIC memory card necessary and it can the same as suggested to the more expensive CPU.

Siemens Simatic 1500 combined with STEP 7 (TIA Portal) can improve machine performance specially when you follow Siemens guidelines like avoid accessing the Data Logs over the web server while the CPU is transferring the data to the Data Logs. Otherwise the time for executing access to the Data Logs can increase greatly in the CPU or Limit the number of Data Logs which you can create with the "DataLogCreate" instruction. The volume of data that can be stored in a Data Log depends here on the space available on the memory card or in the internal load memory of the CPU used. Note that not only the user program but also information like symbols and comments are stored in the load memory of the S7-1500 CPU. This is why a STEP 7 program in a S7-1500 CPU uses significantly more load memory on the memory card than a S7-300 CPU. Memory cards of different memory sizes for sufficient load memory are available for S7-1500 CPUs.

Siemens S7-1500 can Optimize diagnostic concept by efficiently analysing faults using a uniform display concept in the TIA Portal, for example product code 6ES7822-1AA05-0YA5 (SIMATIC STEP 7 Prof. V15.1; Floating License; Engineering Software in TIA Portal), on the HMI panel (e.g. 6AV2123-2DB03-0AX0 SIMATIC HMI basic panel frem KTP400 series with key/touch operation, 4" TFT display with 65536 colours and PROFINET interface). It can constantly and consistently diagnose integrated system without project planning and display error messages even in STOP mode. As well power supply will be required for above products and we can recommend 6ES7505-0KA00-0AB0 SIMATIC S7-1500, System power supply PS 25W 24 V DC, supplies the backplane bus of the S7-1500 with operating voltage as well Load power supply with ordering code 6EP1332-4BA00 SIMATIC PM 1507 24 V/3 A Stabilized power supply for SIMATIC S7-1500 input: 120/230 V AC, output: 24 V DC/3 A . When needed power supply connector 6ES7193-4JB00-0AA0 2x2-pin female connector 2x2-pin female connector ET200S, Interface Module, KP32F, PN-PN coupler Grid size 5.08 mm cage clamp technology, internally bridged, color-coded can be applied. Siemens can also provide FastConnect stripping tool with ordering code 6GK1905-6AA00 which can make life easier. For connection with Ethernet devices or modules cables will be required, for example ordering code 6XV1840-3AH10 - industrial Ethernet FC TP Trailing Cable, 2x2 (PROFINET Type C), TP installation cable for Connection to FC outlet RJ45, for cable carrier applications, 4-core, shielded CAT. 5.

So, as we can see Siemens S7-1500 can be very effective tool to optimize your machine when integrated with TIA Portal and HMI (Human – Machine – Interface) and that is only a glimpse of technical improvements. Siemens has wide and well catalogized datasheets with technical documentation and already configurated CPU’s which will suit every new or updated machines or product lines.
