The costs for the provision of services as well as shortening ofdowntimes in case of malfunctions are becoming more and more important.Therefore manufacturers of plant and machinery are using the fast and inexpensiveon-site diagnostic tools to an increasing extent. Even more efficient:Remote diagnosis by means of radio connection.The diagnosis and service units CANcom, CANmem and CANview not onlysupport the application programmer, but also the end user.RS 232POWER/CAN ANT.Remote diagnosis – online connection around the globeNormally a programming or operational data logging system is directlyconnected to a control system in the machine via a fixed cable connection.To do so the usual interfaces (e.g. RS-232, Ethernet) or field buses (e.g.CAN) are used.In most cases access and data exchange are made via PC or notebook. Forstationary machines and installations the connection is made by means ofthe components installed in the control cabinet.It is more difficult if a system is not in a fixed place, like a mobile machine.The service technicians are usually not on site and if a service is required it isin most cases very time-consuming and expensive.This problem can only be solved by using a wireless connection to the machine.Service and operating data can be exchanged in the open field.Among radio connections the GSM network (Global System for Mobile communication)is currently the best option for telecommunication. GSM offersgood availability and can be used internationally. Furthermore GSM cannotonly transmit language but also data, the latter being used for the connectionto the machine controller.One of the most well-known services of the GSM network is the Short MessageService (SMS). It serves for the exchange of short text messagesbetween GSM units. If the remote station is not available SMS messages arestored with the network provider over a longer period of time and deliveredwhen the receiver is available again.GPRS (General Packet Radio Services) is a new mobile radio technology forfast data transmission. It also uses the GSM radio network. In contrast to thecurrent GSM communication, the data is condensed into packets that can betransmitted via the radio network depending on customer needs and systemcapacity. At the receiver these data packets are reassembled. So GPRSachieves not only higher transmission speeds but also a permanently activeradio connection. The incurred communication cost is only calculated on thebasis of the transmitted data volumes (e.g. new configuration data) andnot on the connection time. Because of the structure of the data packetsthey are exchanged in the network similar to TCP/IP communication. Thisenables, for example, simple access to machine data via the internet.Transmission ofmachine datadirectly from thecontroller.Visit our website: www.ifm.com88
