Q: How many Modbus TCP masters/clients can the MB-GATEWAY support?
A:  Twelve (12) simultaneous TCP connections are maintained. If a 13th master/client attempts to communicate, then the MB-GATEWAY will reset (RST) the oldest TCP connection (i.e. close one master/client's TCP connection).

Q: How can the MB-GATEWAY be recovered if its IP address and/or Ethernet settings make it disappear from NetEdit?
A:  There are two ways to get this back:
 This will cause it to reset all network settings to factory default and flash Status and Error lights. In this mode it should be visible in NetEdit again where you can fix the Ethernet settings, but it will not function properly. So after fixing the settings, repeat the above steps flipping Dip Switch #6 OFF in step (2).

NOTES:
* The "Recover" feature is present in the Module's booter (not firmware), and was put there (and remains) from the very first release
** The "Protect" feature must first be enabled in NetEdit3 Advanced Settings, otherwise this dipswitch can be used as part of the Module ID
RBE (Report By Exception) - Dipswitch must be ON for this to function
IBox (Intelligent Boxes) - Dipswitch must be ON for the ECxxxxxx IBoxes to function
Recover - Dipswitch used to reset IP settings back to factory default on power-up in case device is lost on network
Protect - Dipswitch must be ON to write protect firmware and network, node, peer-to-peer, SMTP (email) configurations
Module ID - Bit-weighted for manual setting of this paramete
Stop Bits - Selects one or two stop bits
Parity - Selects none, odd, or even parity
Baudrate - Selects, software config'd baudrate, or 4800, 9600, 14400, 19200, 38400, 57600, or 115200 baudrate
MB-GATEWAY FAQ0005

Q: Getting, "Illegal Data Address" when Modbus RTU slave is disconnected.
A: Under normal circumstances, this error is due to writing to, or reading from a Modbus address that doesn't exist in the Modbus RTU server device on the MB-GATEWAY serial port. For example, perhaps the MB-GATEWAY is attempting a FC03 (Read Holding Registers) from a Holding Register address 2050 but the Modbus RTU server device only goes to address 2047.

However, there are a few other things that can cause this error to display. For instance, in the following example, the PC is using Modbus Poll to a MB-GATEWAY which, in turn, is talking serially to an H2-SERIO-4 module as its Modbus RTU server device. Notice Autoreads are configured to read from the H2-SERIO-4. The Slave ID being used, however, by Modbus Poll is the MB-GATEWAY's Module ID 1 not the H2-SERIO-4's, which is 2.



In this case, if the serial connection to the H2-SERIO-4 is disconnected, you will see, "Illegal Data Address."

But if you configure the setup like the following instead, and the serial connection to the H2-SERIO-4 is disconnected, then you will not get "Illegal Data Address" as an error but you will get "Memory Parity Error" or "Transaction ID Error" or even "Timeout."



The error messages are not exactly helpful, and obviously point you in the wrong direction. We plan on correcting these and making them more accurate in a future release of MB-GATEWAY firmware.

Q:  Why do I not see my device in NetEdit3? My device does not show up in the list.
A:  Try one or all of the following possible solutions:
  • Solution #1 - Network Adapter (NIC) Issue: In NetEdit3's menu, choose Network --> Adapter, and select something other than Default. You should choose the actual NIC you are using on your PC that is connected to your devices network.
  • Solution #2 - Windows Firewall Issue: On your PC, temporarily switch OFF your Windows Firewall. If you do not want to do this, then in Windows Security, under Firewall & network protection, select "Allow an app through firewall," and add NetEdit3.exe
  • Solution #3 - Network Adapter (NIC) Conflict: On your PC, temporarily Disable all other network adapters (NICs).
  • Solution #4 - Known IP Address: If you know the IP address of your missing device, in NetEdit3's menu, choose Network --> Connect to Single Device, enter in that IP address, then press the <OK> button.
  • Solution #5 - Unknown IP Address: If you do not know the IP address of your missing device, it may be possible to give it one using a utility called from NetEdit3. In NetEdit3's menu, choose Utils --> Start IP Config Tool.

    IPConfig

    - In this tool click once on your adapter at the bottom. This will automatically select the Subnet Mask for you
    - Next, from the label on your device, finish entering the Ethernet Address at the top. The utility needs the rest of this address, or it will not work
    - Next, choose an available IP Address that is on your PC's subnet
    - Press the <Write> button. This will attempt to use raw Ethernet II protocol to set the IP address to what you asked. On some older devices (e.g. H2-ECOM), it might report that it failed, or that it could not find the device, and yet it actually worked
One (or more) of these solutions should cause your device to show up in NetEdit3's list after pressing the <Scan Network> button.
