Read/Write Data Access for Users
Although most data features in FactoryTalk Historian ProcessBook require
read-only access (writing annotations (page 195) from the Details add-in
being one notable exception), the FactoryTalk Historian system
Administrator can configure a user's setup for read-only, read/write, or no
access. For more information, refer to PIBuild:PIServer.txt on
your FactoryTalk Historian server node.
If you want to restrict read and/or write access to FactoryTalk Historian
data, make changes in the CLIENTACCESS section of the file
pisysdat:piserver.dat. For example:
[USERDATABASE]
DEFAULT=PI
[CLIENTACCESS]
DEFAULT=RW
DYAN=R
ERIC=R
JOHN=NONE
The above entries in piserver.dat result in:
 The machines named DYAN and ERIC have only read access to
FactoryTalk Historian data.
 The machine named JOHN does not have any access to FactoryTalk
Historian data.
 All other machines have both read and write access to FactoryTalk
Historian.
The value for the DEFAULT entry is initially set to RW. Otherwise,
existing PINet nodes will not function properly.
If you want to restrict write access from PCs, set the default
CLIENTACCESS to R and add entries to accommodate your PINet
Nodes. For example:
[USERDATABASE]
DEFAULT=PI
