This information is transparent to the end user There can only be one Master in any network but up to 254 Slaves and Repeaters that are synchronized to that Master 3 2 4 3 2 Slave A Slave is responsible for receiving the Masters synchronization pulses and sending back replies when queried by the Master All Slaves that synchronize to the same Master and said to be on the same network The Slave will sync to the Master address specified in the Master ID parameter found in the Roaming section of the menu Alternatively if Roaming is set to Allowed parameter instead this Slave will search for any Master within radio range to lock onto It will lock onto the first available Master it finds within radio range 3 2 4 3 3 Repeater When a radio is configured as a repeater it utilizes Store and Forward to transmit the data beyond the range of a single radio An important note is that all radios in the network must know that there are repeaters so that if they hear a weak signal direct from the master radio repeated by the repeater they do not respond twice This is a Group setting called Repeaters Click the Radio button on Yes if Repeaters are used in the network Repeaters also function as Slaves A Repeater uses store and forward technology that is transparent to the end user so that only a single radio is required for Repeater operation This allows for a cost effective network design and convenience since any Slave location can also function

12. 1 GENERAL OVERVIEW The SMX family of modular wireless I O devices is designed to enable users to easily construct a SCADA or Telemetry system that will fit their specific needs It is compact DIN rail mounted and modular in design and the radio transceiver modules enable a range of up to 20 miles using license free 902 928Mhz Spread Spectrum There are 2 different radio transceivers that can be used in an SMX system the SMX 900 and the SM 900 Their main difference is that the SMX 900 can interface to SMX I O modules and RS 485 RS 422 RS 232 serial devices while the SM 900 can only interface to RS 232 serial devices Other differences are detailed in the Hardware section of this manual The general features of the SMX family are Modbus and Allen Bradley s AB DF1 protocol support Transparent Serial for other protocols Modular I O Expansion module SMX 900 only I O Telemetry SMX 900 only RS 232 RS 485 SMX 900 only RS 422 SMX 900 only ports Up to 254 Slave address range Diagnostic Port SM 900 only OL ES Using SMX 900 or SM 900 the user can easily set up complex Modbus or Allen Bradley DF1 SCADA communication systems SMX 900 and SM 900 transceivers interoperate and communicate seamlessly with each other and SM 900 s are less expensive and generally used when only RS 232 Serial communications is required at the remote site This manual enables a user to configure and install the correct SCADA or Tel
13. 1 Rotary Switch Settings On the top of each I O module except the A8D4 there is an 8 position Rotary switch used to assign a specific register address range to the I O module There is a maximum of 8 ranges indicated by numbers to 8 A range is selected by rotating the switch with a screwdriver until it clicks into the desired position see Fig 4 NOTE The ASD4 module is a special I O module that has no Rotary switch to set Instead the first 5 register address ranges are already pre assigned For each Slave site the maximum number of I O modules is e 8 regular modules or e 1 High Density A8D4 5 positions plus 3 regular modules When an A8D4 is used it automatically takes up positions 1 to 5 leaving only positions 6 to 8 to choose for any remaining I O module In general once an I O module is set to a switch position no other module can be assigned to that position For instance if a DIS module is assigned to position 1 then no other modules can be assigned to position 1 Full details of the register addresses are given in Appendix C Modbus and AB I O Module Address Mapping Here Module is equivalent to Rotary Switch position Bentek Systems Ltd page 31 of 71 SMX 900 SM900 User Manual V1 00A Successive modules must be assigned to the remaining positions that are available See configuration example 1 for a detailed example WARNING Setting 2 I O modules to the same rotary switch position register address will
