Hi, it is 6ES7414-2XG03-0AB0 for S7-400 and for S7-300 I have only photo w/o model number but it is CPU315-DP. Actually I would not like to touch the SW & HW config, and I would not have been able even if I had this wish. No memory cards and download protection exists(I've consulted with local SI) The PCLs control old machines that would not be modified ever. My idea is to remotely monitor only inputs and outputs states via some iso-over-tcp gateway to MPI. Like this one. Once I've connected to the S7-300 via similar gateway. So my plan is to "probe" default bus net ids for the PLC and connect via the gateway. Another option - is second HMI panel from Delta Electronics or Wientek with VNC support, so I could remotly observe the equipment. BTW, do you know if the S7 MPI connection has an option to "protect" communication with password or other means to protect from unwanted nodes? I've heard from some SI about MPI connection with "authorize" option and "no auth" option. Thanks in advance |
