 Posted: 20/02/2014 08:42 Post subject: Changing the Twincat PLC time? |
 |
|
Hi All,
I am frankly quite new to PLC's and HMIs, and have been tasked to change the time of the clock in the PLC. We currently are using Beckhoff TwinCAT PLC 2.10 with Proficy HMI/Scada ifix 4.0. The project is currently running on a production line, the project was completed by another company, who is very difficult to get a hold of for support.
Currently our production reports show downtime to be off by 1 hour. The HMI time is correct but the PLC time is probably off.
1. Where would I find the date and time info?
2. Once I find and adjust the time, I assume I need to rebuild the project, can you you provide the basic steps to get the time adjusted?
Sorry for such a newbie question |

Some hints in Beckoff infosys...
FUNCTION_BLOCK NT_SetLocalTime
NT_SetLocalTime
The function block "NT_SetLocalTime" sets the local Windows system time of the TwinCAT system (the local Windows system time is displayed in the task bar).
VAR_INPUT
| Code: | VAR_INPUT
NETID :T_AmsNetId;
START :BOOL;
TIMESTR :TIMESTRUCT;
TMOUT :TIME := DEFAULT_ADS_TIMEOUT; |

FUNCTION_BLOCK NT_GetTime
NT_GetTime
The local Windows system time of a TwinCAT system can be obtained using the "NT_GetTime" function block (the local Windows system time is displayed in the task bar). The year, month, day, day of the week, hour, minute, second an millisecond are placed in the variables in the structure TIMESTRUCT. Internally, an instance of the ADSREAD function block is called.
VAR_INPUT

NETID :T_AmsNetId;
START :BOOL;
TMOUT :TIME := DEFAULT_ADS_TIMEOUT; |

FUNCTION_BLOCK FB_LocalSystemTime
FB_LocalSystemTime
In some applications the local Windows system time is synchronised via the SNTP time server or a radio clock. The local Windows system time (the local Windows system time is displayed in the task bar) often has to be used in the PLC (e.g. for time stamp log messages to the HMI). For such applications the FB_LocalSystemTime function block can be useful.
