This new CPU Module brings many new capabilities to the successful SMAR LC700 Hybrid Controller. Read the lines below and understand why the SMAR CPU-700E3 is being considered as a break-through for a control industry device.

The CPU-700E3 comes to cover the necessity of larger configurations, handles a complete online editing, has more discrete I/O points available and the user can optimize the communication variable list for faster variable scanning with a HMI (human-machine interface) operating software. All this plus the revolutionary "Instant Recovery" feature that allows a fast return to the last working configuration.

Larger Configurations

Programming (configuration) memory increased from 30K to 52Kbytes*. This memory increase allows applications with a significant leap on the number of Ladder Networks supporting Relay, Coils and Function Blocks.

The number of discrete I/O points jumps from 1024 to 2000. Any combination between physical and virtual points. Larger and more complex configurations can now be accommodated, in this new version.

* The memory available for configuration is 46Kbytes when using the redundancy feature of the CPU-700E3R.

Complete Online Editing

This is really a win-win feature. Users can change anything in the LC700 configuration ONLINE and send to the device without resetting the current control.

This feature brings a tremendous peace of mind for the plant start-up or in the "debugging" process.

The LC700 Online Editing capability is really broad. The user can edit Relays, Coils, Function Blocks, add/remove logic networks and even I/O Modules.

For instance, a couple of new control loops and interlocks can be added to the configuration without harming the already existing ones.

Faster Communication Response

New features have been added to increase the communication network through-out. The CPU-700E3 treats pending request from all the communication ports (P1, P2 and P3) in the same control cycle. This new characteristic improves the response time when more than one port is used.

Another break-through is the Modbus Cross Table (MCT) technology. It allows alignment in sequence for the most used variables to be integrated in the transactions with a HMI system. In this way, variables are seen as an easily accessible group and Modbus drivers can access them using less amounts of commands.

Tracking Changes

The Configurator (CONF700 v8) keeps a mark on every change in the Logic Ladder Network and in the I/O Module Table.

Instant Recovery

Lets suppose that right after sending modifications Online we notice instability or any malfunction in the process. This is a typical situation of panic that can now be avoided with this exclusive feature. With a simple command from the Configurator we can revert the configuration to the old one and rethink our modifications to try again!
