Configure Computer Role

Use the Computer Role Setup page to specify the role of the computer running Citect SCADA. Select one of the options described below.

Note: In order to use Citect SCADA's multi-process capabilities, networking needs to be enabled.

Option	Description
Server and Control Client	This computer will be a standalone or networked I/O Server and Control ClientThe interface between the runtime system and an operator. If you are using Citect SCADA on a network, all computers (on the network) are control clients.. This option is disabled if this computer has no Server components assigned to it to run. Selecting this option enables the Multi-Process check box. Select the Multi-Process check box to separate your client and server components into individual processes. This option can be used for distributing the components across multiple CPUs. If you leave the Multi-Process check box unselected, Citect SCADA will run the client and server components in one process. If the Multi-Process check box is selected the [General]MultiProcess parameter in the Citect.ini file is saved with the value 1. If not selected, the parameter is saved with the value 0.
Control Client	This computer will only be a Control Client. This option is disabled if this computer has been assigned a Server component to run. Selecting this option enables the full server license check box. Select the full server license check box if you want this Control Client to use a full (server) license, as opposed to a client license. This sets the [Client]FullLicense parameter in the Citect.ini file to 1 (the default value is 0). Generally, you would not allocate a full server license to a client as there is no difference in functionality between the two licenses. Allocate a full server license if you have insufficient client licenses available, or for some other specific need.
View-only Client	This computer will only be a View-only ClientA computer configured with view-only access to the runtime system. No control of the system is possible, but full access to data monitoring is permitted.. This read only option is disabled if this computer has been assigned a Server component to run.

Description

Server and Control Client

This computer will be a standalone or networked I/O Server and Control ClientThe interface between the runtime system and an operator. If you are using Citect SCADA on a network, all computers (on the network) are control clients.. This option is disabled if this computer has no Server components assigned to it to run. Selecting this option enables the Multi-Process check box.

Select the Multi-Process check box to separate your client and server components into individual processes. This option can be used for distributing the components across multiple CPUs.

If you leave the Multi-Process check box unselected, Citect SCADA will run the client and server components in one process.

If the Multi-Process check box is selected the [General]MultiProcess parameter in the Citect.ini file is saved with the value 1. If not selected, the parameter is saved with the value 0.

Control Client

This computer will only be a Control Client. This option is disabled if this computer has been assigned a Server component to run. Selecting this option enables the full server license check box.

Select the full server license check box if you want this Control Client to use a full (server) license, as opposed to a client license. This sets the [Client]FullLicense parameter in the Citect.ini file to 1 (the default value is 0). Generally, you would not allocate a full server license to a client as there is no difference in functionality between the two licenses. Allocate a full server license if you have insufficient client licenses available, or for some other specific need.

View-only Client

This computer will only be a View-only ClientA computer configured with view-only access to the runtime system. No control of the system is possible, but full access to data monitoring is permitted.. This read only option is disabled if this computer has been assigned a Server component to run.

Some of these options may be disabled depending on what servers have been configured to run on this computer. The Setup Wizard cross-references your computer's network identification with the network addresses configured for each server in your project configuration.
