from aspect/connectivity sever or other client station can not send commands to dual safeguard 400 controller
on my job upgrade Advacommand 1.7 for windows NT to System 800xA Software.my control system is Advant OCS with Master Software. before i have 4 operatore workstation(OS500 Advant station), 2 Engineering station(OS500 Advant station), and one Historian station(IMS).
after upgrade only dula servers(primary aspect/connectivity server and secondary aspect/connectivity server) conected to MB300 Control network via two PU410 RTA Units. other stations after upgrading connect to TCP/IP Network and workeplaces access to process data via server. during configure of RTA Units, take node numbers of 82 and 83 by defualte. Servers and Client Stations con communicate to process control node(PCS) and process shut down system node(PSS) and operatore can send commands to these nodes. but for Dual Safeguard 400 nodes, operator can not send any commands to Dual Safeguard nodes(on/off, start/stop, set inhibit, block input and so on). of course on workplace graphics, objects can read data from Dual Safeguard 400 .
after i change node number of PU410 RTA Units(node number 82 and 83) to the node numbers(node number 4 and 5 ) that old operator stations in Advacommand used this node numbers, from all stations same servers ans clients operator can send commands to Dual Safeguard 400 .
do need that assign the node numbers of PU410 RTA Units(node numbers of 82 and 83) to Dual Safeguard 400 some where like in DATA BASE or in Dual Safeguard File ?
It is issue with Safeguard configuration file.
Open the Safeguard Configurationfile and check "OS write access" under the tab "By-pass managenent" for the OS Numbers 4 & 5 from which only it allows the commands.
Remove the node numbers from the safeguard configuration file and load the modified configuration file to Safeguard. So that it will allow to Block or any commands from any work station.
Since it is 800xA, no need to use this function "OS write access" to restrict the operator actions, instaed the 800xA security setting can be configured to contro the operator or Engineer actions.
