The Pentra PLC range includes 12 CPU modules that are compatible with the company's current MicroSmart input/output modules and are the same physical size as the present CPUs.
New from Idec, the Pentra PLC range includes 12 CPU modules that are compatible with the company's current MicroSmart input/output modules and are the same physical size as the present CPUs.
More than double the memory size, up to 275 times faster processing speed and the capability for floating point maths means the Pentra can handle most complex tasks that are thrown at it.
The CPU has high speed counter inputs counting at a maximum frequency of 100kHz with 32bit word comparisons and PID with an advanced auto tune feature are other improved functions.
Master and slave expansion modules have been introduced enabling up to a maximum of 512 I/Os to be connected via an expansion cable if necessary.
This means the Pentra can be accommodated in narrow width 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 new web server, up to two AS-I network modules can be addressed and the Pentra has the ability to operate as a Modbus master or slave.
The upgraded programming software, WindLDR V5.0, gives the user the options of online editing and runtime program downloading which means the Pentra does not have to stop its scan while programming modifications are undertaken.
If the user wants to develop a program and the PLC is not available for testing, then program simulation can be run directly on the PC.
