6. 5 The Profibus Network Slave Module The Profibus DP NSM IC200BEM002 provides a basic interface to a Profibus DP network It operates as a slave on the network automatically exchanging data with a master device The NSM has no bus access rights it may only acknowledge received messages or transmit messages to a master upon request The Network Slave Module can read up to 244 bytes of input data from the network and send up to 244 bytes of output data The total combined amount of inputs plus outputs for the NSM is 384 bytes IC200BEM002 ok S Profibus DP co NETWORK SLAVE IND CONT EQ FOR HAZ LOC CLASS IDIV 2GROUPS ABCD CO Ambient 60C CLASS I ZONE 2 GROUP IIC a Ex nA II 0C lt To lt 60C ExnV Il HH Demko No 98Y 125014 y a Ws mo we CE T HEHEHEHEH EEEH y Pa 26 le O o oO l Lai lt 5 LEDs indicate the presence of power and show the network communications status of the Network Slave Module The 9 pin D shell connector is used to connect the bus cable GFK 1534B 5 NSM Specifications I O data 384 bytes maximum Up to 244 bytes of inputs or 244 bytes of outputs Profibus network address 1 to 125 Software configurable
7. Software configuration provides greater flexibility than autoconfiguration in setting up an I O Station Software configuration is done using the Remote I O Manager configuration software Autoconfiguration of the Profibus NIU and I O Station Autoconfiguration provides a default configuration for the NIU and I O Station and does not require the use of a programmer I O modules that have software configurable features always use their default settings when autoconfigured Profibus network configuration The Profibus NIU must also be configured as a slave on the Profibus Network Before a controller can communicate with the NIU it must send the NIU a configuration message NOTE Profibus network configuration of a Profibus Network Slave module is discussed in chapter 5 4 1 Using Autoconfiguration or Programmer Configuration The Profibus NIU and I O Station can be either autoconfigured or configured from a programmer using the Remote I O Manager configuration software The choice of which configuration method to use depends on the nature of the system Autoconfiguration Autoconfiguration is done by the NIU itself It provides a default configuration for the NIU and I O Station and does not require the use of a programmer If there is not a stored configuration already present at powerup the NIU sees which modules are installed and automatically creates a configuration for the I O Station I O modules that have software configura
