9.2 MODEM MD720
Description
The SINUMERIK 828D can be optionally equipped with the MD720 GPRS/GSM modem. This
optional hardware module makes it possible to exchange SMS messages with a cell phone
on the basis of the GSM standard.
In addition to error messages, it is also possible to transmit operating states such as the
machining status, tool wear limits or measuring process results. Using operating screens, it is
very easy to assign specific information to specific cell phones.
Please ensure that the antenna required for data transmission (supplied by the manufacturer)
is suitably located on the machine to achieve the best transmission/receiving conditions.
Connection to the SINUMERIK 828D uses an RS232 modem cable. Please note that optimum
transmission quality can only be guaranteed if the cable is no more than 3 m long.
A SIM card is not included in the modem scope of delivery. The users have to choose their
own cell phone contract.
