8. Note The Global Control command as set in the CIO words is transferred to the Unit together with the I O data but the Global Control command is sent over the PROFIBUS network following the I O data The Freeze command forces an immediate update of the PROFIBUS transmission buffers in the slave device with the last input value sampled This input data is then transferred to the PROFIBUS Master Unit with the next I O data exchange cycle 105 Operating the Network Section 3 6 Sync Unsync commands Sending a Global Control Sync command to a slave device has the following effect e The slave device will update its physical outputs only once with the last received PROFIBUS output data despite new output data being received from the PROFIBUS Master Unit e If a new Global Control Sync command is sent the slave device will update its physical outputs only once with the most recent received out put data e If a Global Control Unsync command is sent the slave device will revert back to its original situation and transfer updated output information to the Master Unit with each subsequent I O data exchange message Note If a Global Control command contains both a Sync and an Unsync command the Unsync will prevail The figure shown below illustrates the Sync Unsync feature as implemented by the CS1 CJ1W PRM21 PROFIBUS Master Unit Global Control Sync command Global Control Unsync command PLC Cycle PROFIBUS C

When Auto Addressing is being enabled a warning message is displayed informing the user of the effects of enabling Auto Addressing Enabling Auto Addressing has the immediate effect of re allocating I O mod ules of an existing configuration within each Input Output area The I O mod ules are re mapped according to the algorithm described above Disabling Auto Addressing has no immediate effect on an existing I O map ping A disabled Auto Addressing feature has the following effects on I O mapping e When adding new slave devices or new I O modules to an existing slave configuration the I O modules will be mapped to the first I O areas but the modules will be appended to the existing I O mapping e When deleting a slave device from the network configuration or deleting I O modules from a slave device the deleted I O modules will leave gaps behind in the already existing I O mapping If after deleting an I O module a slave device still has more than one module configured but these mod ules are not in the same place the DTM will attempt to remap them together Changing the address of a slave device of which already an I O mapping exists has no effect on the existing mapping Selecting an additional I O module for a slave device in the presence of already allocated I O modules will cause a complete re map of all exist ing modules if the total I O does not fit within the space it is already occu pying The modules are re mapped
