2. 8 3 Call to the data centre The calls to the data centre are made by PlantWatch when the remote signalling conditions exist see Chap Alarm management The purpose of the call is to transfer the updated alarm log to the centre PlantWatch also calls the centre to download the variables log The latter call is made when the remaining space for saving the variables log falls below 30 of the space available If the call and the download operation are successful PlantWatch considers the free space as being 100 If PlantWatch cannot perform the download before the space falls below 20 a serious alarm is generated and this is signalled by fax and or SMS and the activation of the alarm relay a second alarm notifies the user when the space reaches zero and the data not yet stored will be irreversibly lost The variable that indicates the space occupied can only be reset if the password sent by the remote PC allows its authorisation This ensures that any other computers making the call can download the log resident in PlantWatch without compromising the continuity of the procedures for saving the logs to the centre s PC All calls for other reasons from PlantWatch to the authorised centre and vice versa include the downloading of the data and the setting of the free space to 100 8 4 Activation of the relays The relay is activated by PlantWatch when the remote signalling condition exists see par 5 The configuration parameters allow
