Cache File Path

Folder name where cache files will be read and saved. There are 3 types of cache files:

- GUID File (MetasysGUID.txt): Contains the internal codes of each Metasys object, which are stored at this file to speed up the startup process.

- Command and State Cache Files (DeviceName_MetasysStateCache.txt): Contains the description of commands and states of the objects marked with N1>0, stored in a cache file per NAE controller, to speed up the startup and translation process for the numeric values 0 or 1.

- State words (MetasysState0.txt and MetasysState1.txt): contains the state names corresponding to the values 0 and 1 respectively.

If the cache file path is not informed, the files will saved at the same folder where the driver dll is located.

Force New Login After (s)

Force new login independently of the token expire time. 0 = disable

Protocol Version

V3: Uses only polling for reading

V4: Allows polling and events (subscriptions)

Read Method

Polling: performs tag readings by polling. Can be used both V3 and V4;

Events: performs tag readings by subscriptions and can be used only with V4;

ByTag(N2): Allows choosing the read method by tag at the N2 parameter (0 = polling, 1 = events). It can be used only with V4.

Subscription Renew (s)

When a tag is read by subscription/events, if its value doesn´t change during this interval (in seconds). a new subscription is requested, which forces receiving a new update. If the received value is the same as the current value, the tag timestamp will not be updated, except if the EnableDeadBand property is FALSE.

Polling Options

Options related to polling reading

Items per Read Request

Tells how many items can be added to the same read request. Minimum value is 1. This property is also used to define how many items can be subscribed in a single subscription request.

Inter-Request Delay (ms)

Informs a default delay in miliseconds between read requests for all NAE´s. This delay will be used if a NAE doesn´t have its own delay informed at the tag InterReqDelayMS.

Force New Login After Consec Errors

Force new login after a number of consecutive errors. 0 = disable

Force New Login with Read Error Rate > %

Force new login if error rate (in %) is greater than what is informed. 0 = disable

Read Ahead After Cmd - Wait Time (s)
