Power-over-Ethernet may be ordered on the four and eight port models. The ModGate Plus Gateways support serial speed up to 115200 bps, which is a restriction of Modbus. In RS232 mode the technical limit is 1000 kbps, used as RS485 the serial port can operate up to 3 Mbps.

Page 13: Hardware Description
Oﬀ Table 6: Switch Conﬁgurations By default the ModGate Plus Gateway uses DHCP to get a valid IP Address. When the Gateway is conﬁgured for a static but now unknown address, one can switch to Conﬁguration IP temporarily setting it to 192.168.254.254. Then access via webbrowser is possible for ﬁnal conﬁguration. If DHCP fails it will also respond on 192.168.254.254.

LED will blink. It depends on your network whether a 100 Mbit or a 10 Mbit connect will be established. A 100 Mbit net causes the Speed LED on ModGate Plus (green) to light, otherwise it will remain dark.
Page 16: Power Supply
Table 11: Green LED Function 3.6. Power Supply The ModGate Plus device is powered by a single 9-54V power supply. It requires 300 mA up to 600 mA of current, depending on the device type and voltage supplied. A suitable power supply adapter is available as optional accessory.

Page 19: Configuration
But this is not always the situation. The ModGate Plus may use DHCP, which is also the default conﬁguration. If a DHCP server is available, it will assign an IP Address from a conﬁgured pool. At ﬁrst this address is not known to the user, since he can not access the DHCP servers log ﬁle.
Page 20: Status
5.1.1. Status Figure 9: Status information The type of ModGate Plus is shown as the Model Name. For identiﬁcation the Serial Number and MAC-Address are also given. Since such an address must be unique for all devices on the world, this is suitable to check if the conﬁguration starts on the correct device. And last the Firmware Version is presented.

Page 23 Therefore it is replaced by the mode of Access Point here, which also allows a PC to establish a direct connection to the ModGate Plus. In Infrastructure Mode all communication is sent via an Access Point on-site, which operates as the central hub of the Radio Cell.

Manual. If Infrastructure is chosen it is very likely Auto (DHCP) has to be used. When ModGate Plus has access to the WLAN radio cell, this network interface operates similar to Ethernet. Meaning all IP traﬃc operates exactly the same on Ethernet or WLAN. This results in a conﬁguration parallel to Ethernet.
Page 25: Online Firmware Update
If the newest ﬁrmware is already running, it will inform you of that. If the Internet is not accessible by the ModGate Plus or fails for other reasons, it shows “Getting new version info failed. Please check for a new version manually.” .
Page 26: Modbus Configuration
DirectMappingMode operates. However in many installations there is a ModGate Plus with a single serial port only. This Gateway is contacted by only one Master via TCP. Naturally all data coming from TCP must be sent to the serial port, and vice versa.
Page 27: Configuration Of Tcp Connections
Deﬁned TCP connections can fulﬁll two separate functions: 1. They can be used to restrict the access from which IP addresses the ModGate Plus can be used. One would uncheck Allow unknown clients (See 6.3) and deﬁne all Inbound TCP connections allowed access.

Modbus/TCP Slaves (Server). Inbound expects a connection to the ModGate Plus on its ListenPort what a Modbus/TCP Master (Client) would do. The Port can be set for outbound connections; otherwise it will show the TCP Port on which the ModGate Plus listens. There are two types of ConnectMode available: •...

(Mapping of Modbus devices to serial ports or TCP connections) or LineMappingMode (Map- ping of serial ports to TCP connections). Allow unknown clients Enables all stations to connect to ModGate Plus without prior conﬁgura- tion as an allowed source for data.
Page 30: Devices To Serial Or Tcp (Direct Mapping)
– TCP (Gateway) allows to have multiple Modbus devices on one TCP Connection because the Modbus Device ID is sent in outgoing Modbus/TCP packets. This supports TCP to serial gateways like ModGate Plus. • Destination ID: Depending on the Destination Type this is either a Serial Port ID or a TCP Connection ID.
Page 31: Serial To Tcp (Line Mapping)
If Allow unknown clients is enabled (6.3) on a single port device, there is no need to conﬁgure a mapping. On a multi-port model all traﬃc from unknown clients is forwared to serial port 1. June 2018 ModGate Plus User Manual...

ﬂag, the settings belonging to the currently inactive mode are ignored (e.g. when in LineMappingMode all mappings that were speciﬁed for DirectMappingMode are ignored). ModGate Plus treats lines as comments when they start with the hash character “#”.

Modbus/TCP as intermediate. Then these requests use the target queue as well. 7.2. Conversion of Serial Line Parameters On ModGate Plus models with multiple serial lines a master on a serial port can address slaves on the other serial ports. The DirectMappingMode allows for that conﬁguration. The involved serial lines do not need to share the conﬁguration parameters.
Page 36: Example Configurations
8 Example Conﬁgurations 8. Example Conﬁgurations The ModGate Plus are intended to convert from Modbus on serial lines (RTU or ASCII) to Mod- bus/TCP, and vice versa. This chapter will show some fairly often used installation variants. The requirements of the application are given ﬁrst, then the suggested conﬁguration of ModGate Plus with an explanation on why these parameters are selected.
Page 37: How This Works
The conﬁguration above sends all requests coming from any TCP-Master to the ﬁrst serial port. On a single port ModGate Plus this is not a problem. A multi-port device only allows to use the ﬁrst serial port in this way because the information how to forward arriving requests is not speciﬁed.
Page 38: How This Works
IP/Host is the deﬁnition of the TCP-Master to get access to a serial line. Direction is Inbound because the TCP-Master initiates the connection. Port shows 502 as the TCP port on which the ModGate Plus listens. Once such deﬁnitions exist for all planned TCP-Masters, the Line Mapping is to be deﬁned. See...

Modbus Device IDs, the request is considered targeted to a device on the serial line. In that case it is ignored. But if the ID is found among the conﬁguration, the ModGate Plus opens a TCP connection to the Modbus/TCP device if the connection does not exist yet (This is controlled by the Auto conﬁgu- ration).
Page 41: Using Modbus/Tcp To Monitor A Serial Modbus Line
The existing serial line is cut between the Master and the Slave devices. The Master connects to serial port one of the ModGate Plus, while the remaining line with the Slaves is connected to the second serial port. The ModGate Plus will then forward the requests from the Master to the second serial port, returning the responses in the opposite direction.
Page 42: How This Works
Plus. It extracts the Modbus ID from the request, and as per conﬁguration this Destination ID is deﬁned. So the ModGate Plus forwards the request to the serial port 2, where the Slave devices receive the data. The device with this Modbus ID sends the response, which in turn is forwarded back to port 1.

Gateway L for Local. Other ModGate Plus are referenced as Gateway R (R2, R3, ...) for Remote, and these are connected to the new remote devices. The ModGate Plus Gateway L is conﬁgured for Direct Mapping, and has deﬁned TCP connections to the Gateways referenced as R.

Plus Gateway L also; the Master sends requests to many Modbus IDs. When such an ID is not conﬁgured in Gateway L, the ModGate Plus simply drops the request. The target is on the serial line, and will eventually send the response.

Modbus devices communicating via RS232; in such a situation only a single device per serial port is possible. For example a ModGate Plus 413 can connect to four devices RS232, or fewer plus several other devices via RS485 on one port.
