With Lloyds Register and ABS* approval, the MicroSmart and Pentra PLCs are now certified for use in marine vessels and offshore structures. These approvals make it possible for IDEC MicroSmart/Pentra PLCs to be utilised in marine applications, especially in engine room control.
MicroSmart has always meant speed, flexibility and power, and now with the addition of the Pentra range, adaptability and functionality have been increased as well. The Pentra packs plenty of features into a small footprint to create a powerful controller with a response time up to 16 times faster than leading competitors' PLCs. Furthermore, with 32 bit data processing and the capability of floating point maths to seven decimal places, the Pentra can handle most complex tasks.
The CPU has high-speed counter inputs counting at a maximum frequency of 100kHz with 32 bit word comparisons and PID with an advanced auto-tune feature as standard. Master and slave expansion modules are available, enabling up to a maximum of 512 I/O to be connected via an expansion cable if necessary. This means the Pentra can be accommodated in narrow cabinets, as the master/slave units can be situated anywhere in the I/O range.
Network capability has not been ignored either: EtherNet connectivity is possible via the web server module, up to two AS-i network modules can be addressed and the Pentra has the ability to operate as a Modbus master or slave. By adding extra modules up to seven serial ports can be connected, giving access to bar code readers, printers, displays or any RS232C-compatible device.
The upgraded programming software, WindLDR V5.30, gives users the options of online editing and runtime programme downloading - which means the Pentra does not have to stop its scan while programming modifications are performed. If a user wants to develop a programme and the PLC is not available for testing, then the programme simulation feature can be used directly on the PC - which is a major advantage for application development and testing.
