SiteManager Installer 2.2. Deciding a Device connection method Note: The SiteManager can also provide access to serial devices or USB devices, by attaching them to the RS232 DB9 connector, or the USB con- nector of the SiteManager. The following will concentrate on Ethernet devic- es only. 14. The typical way of deploying a SiteManager and the devices to be man- aged, is to utilize the SiteManager’s ability to completely isolate the de- vices from the corporate network, like this (IP addresses are just examples): IP 10.0.0.2 HINT: The machine depicted as 10.0.0.2, can be attached through a switch, or di- rectly with an Ethernet cable to a DEV port.
Optionally, the SiteManager can be configured to assign the address to the devices on the DEV ports by DHCP. ( /24 noted after after the IP address is just the standard TCP notation of a subnet mask of 255.255.255.0) 15. You can, however, also monitor a device already on the corporate net- work (the Ethernet Uplink side), and no further network configuration of ports are required on the SiteManager (if you are using Uplink2 to con- nect a 3G/GPRS modem, you will have to connect equipment on the DEV port as shown above, and configure the DEV port IP settings corre- spondingly) 192.168.2.2/24 192.168.2.100/24 NOTE:
The machine depicted represents the network device you want to use as “remote monitored device” for this exercise. You can, however, use any IP enabled device, such as a PLC, HMI or even a PC or a printer. In the following we are using a PLC at- tached on the DEV side of the SiteManager. 16. IMPORTANT: 192.168.2.2/24 DO NOT CONNECT THE DEV AND UPLINK1 PORTS TO THE SAME PHYSICAL NETWORK DO NOT ASSIGN DEV ADDRESS IN THE SAME LOGICAL NETWORK AS UPLINK1 192.168.2.5/24 Secomea GateManager5 BASIC Guide Page 12 of 26 192.168.2.2/24
