It is always better in the long run to upgrade your controls. Obsolete parts are a hassle to maintain and expensive to procure. In time upgradation not only saves you from unexpected downtimes, but also provides opportunity to improve upon machine knowledge. C&M can design a new control system to interface with your existing electrical devices or, for those with older systems that have obsolete or worn devices. We can design and build a new enclosure with all new devices.

Simatic S7-300
Introduction SIMATIC S7-300: The Modular Controller for innovative system solutions in the manufacturing industry SIMATIC S7-300 is the best-selling controller of Totally integrated Automation spectrum with a host of successful reference applications worldwide for the most varied industrial sectors. Manufacturing Engineering Automotive industry General machine construction Special-purpose machine manufacturing Standard mechanical equipment manufacture, OEMs Plastic processing Packaging industry Food, beverages and tobacco industries Process engineering The S7-300 enables space-saving and modular configurations. In addition to the modules only a DIN rail is required for hooking in the modules and screwing them into place. If the automation task requires more than 8 modules, the central controller (CC) of the S7-300 can be expanded using expansion units (EUs) Up to 32 modules can be used in the central rack and up to 8 per expansion unit. Interface Modules (IMs) handle communication between the individual racks autonomously. In a single-tiered configuration, this results in a maximum configuration of 256 I/O, and in multi-tiered configurations up to 1024 I/O. In distributed configurations with PROFIBUS DP, 65536 I/O connections are possible. The slots are freely addressable, that is, there are no slot rules.Module range

Signal Modules
Signal modules are the interface of SIMATIC S7-300 to the process. A host of different digital and analog modules provide exactly the inputs/outputs required for each task.
Digital and analog modules differ as regards the number of channels, voltage and current ranges, electrical isolation, diagnostics and alarm functions, etc.

Special Functions Module & Communications Processors
SIMATIC S7-300
Point-to-Point link via communications processors (CPs) is an extremely powerful and low cost alternative to bus-systems. The advantage of point-to-point links over bus systems is especially pronounced when only a few (RS485) devices are to be connected to the SIMATIC S7.
The CPs can also economically connect third party systems to the SIMATIC S7. Thanks to the great flexibility of the CPs different physical transmission media, speeds or even customized transmission protocols can be implemented.
The configuring data are stored in a system data block stored in the CPU. When modules are replaced, the new module is therefore immediately ready for use.

These exception-based assessments are a quick and inexpensive way to audit a machine /work cell to determine the obvious points of operation and power transmission hazards. The result of the hazard assessment is a concise report that identifies the location of each observed hazard and provides a rough budgetary estimate for safeguarding. The hazard assessment will also provide:
- General recommendations on how to guard a machine/work cell
- A prioritization plan for your machine safeguarding project when many unique machines need to be evaluated and upgraded
- The unbiased, third party opinion of a machine safety consultant with the required knowledge of relevant safety standards, best practices and current safeguarding technology.
