Programmable Logic Controllers handle 8-2,048 I/O points.
January 31, 2007 -
Available in 4-, 6-, 8-, and 12-slot versions, EZPLCs can handle up to 2,048 I/O points by communicating through RS485 via Modbus RTU or through Ethernet port via Modbus TCP/IP. Each slot handles up to 8 I/O points, and distributed PLC scheme enables products to be operated from master PLC. Also included, EZPLC Programming Software allows all EZPLCs in network to be programmed from any Ethernet port in network or RS232 port on PLC designated as master.

EZPLC Can Now Handle 8 - 2048 I/O Points, Introducing New Distributed PLC Programming Software
EZPLCs can now handle 8 to 2048 I/O's with highest flexibility. This is possible by communicating multiple EZPLCs through RS485 via Modbus RTU or through Ethernet port via Modbus TCP/IP. EZPLC is available in 4 base models: 4 slot, 6 slot, 8 slot and 12 slot. Each slot can handle a maximum of up to 8 I/O points.
The Distributed PLC scheme of EZPLC makes these little, yet extremely powerful, PLCs to be operated from a master PLC which handles all the logic as well as individual PLCs executing their own local logic and yet communicating with the master PLC.
Along with this feature we are also introducing an upgrade to the EZPLC Programming Software that allows all the EZPLCs in a network to be programmed from any one of the Ethernet ports in the network or even the RS232 port on the PLC designated as the master. This new firmware and software upgrade, Revision 2.0, eliminates the need to use Modbus protocols to implement the distributed structure. Instead it handles the network communication using an internal EZ protocol. This software is currently available as a "Beta" version and is scheduled for a full release by the end of Jan, 2007.
The same feature has been included in EZTextPLC's and EZTouchPLC's. These integrated HMI and PLC controls can now handle 32, 48 or 64 local I/Os as well as expand up to 2048 I/O points in the system.
