Alll the M258 are powered with 24 VDC. # This first model has 42 digital IO # The second model has 42 digital IO, 4 analog inputs and 2 PCI slots allowing adding up 2 communication module as RS232 serial line or RS485 serial line limited to 1 serial line communication module or a Profibus-DP slave. * Four reference of the Modicon M258 have the same characteristics of the 2 previous model excepted the CANopen Master is embedded and # one model has 12 relays outputs with 2 PCI slots for optional communication # These two models have 4 analog inputs embedded and one have 66 discrete IO embedded. * The Modicon M258 range differ in the number/type of the IO and the communication capability. Here we see an overview of the M258 features with : # Local IO including 10 fast inputs and 4 fast outputs and removable terminal blocks for all IO. # A display unit showing the controller status and the IO states # A USB port to download and upload the application and the firmware # An embedded CANopen master depending of the model # One RJ45 connector for connecting a RS232/RS485 serial link for the ASCII, Modbus or SoMachine protocols and On RJ45 connector for connecting an Ethernet network supporting both the Modbus TCP and Ethernet IP protocol # 2 PCI slot for optional communication module depending of the model # 24 VDC power block for the CPU, the standard IO and the fast IO # Extension of the number of IO by the a
