Parameters > Citect.ini File Parameters > LAN Parameters > [LAN]ReadPool


The number of receive message buffers used by CitectSCADA. If you get the error message "Out of buffers" on a server or LAN device, increase this parameter. You might also see the message in the CitectSCADA Kernel or the SYSLOG.DAT file, "Out of buffers" - if so, increase this parameter.

You should only need to increase this value if you have a large, heavily loaded network system (typically greater than 10 CitectSCADA clients, with greater than 10,000 I/O points). If you have a smaller system and you are getting the above errors, you could have a problem with your LAN hardware or configuration.

Allowable Values: 16 to 32760

Default Value: 1024
