Hi, Do Ineed an EM 277 to connect the PLC to HMI or can I connect directly to onboard port (any S7-200). Thanks. |

Em277 is only to configure ur s7200 plc as slave to any master plc like 300 400 1500 or 1200 in Dp network.. For HMI communication simple on board 485 port itself is enough. s7200_system_manual_pinout.pdf Regards, Nelliyan.G |

Hello, And have a look here: Which HMI components can you connect with S7-200 CPU and what should you watch out for when doing so? Regards, Marcjan |
