Hi Adrian,
I've used 'dbr' command on IOC1 and this is the out for Timestamp_from_IOC1:
ioc > dbpr MBT-RBN:TMG-EVR-01:Timestamp_from_IOC1 10
ACKS: NO_ALARM ACKT: YES APST: On Change ASG:
ASP: (nil) BKPT: 00 DESC: DISA: 0
DISP: 0 DISS: NO_ALARM DISV: 1 DPVT: 0x153cf30
DSET: 0x7f5fc4122160 DTYP: Obj Prop string
EVNT: FLNK:DB_LINK MBT-RBN:TMG-EVR-01:TimeErr-I
INP:INST_IO @OBJ=EVR-MTCA, PROP=NextSecond LCNT: 0

MLIS: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

PROC: 0 PUTF: 0 RDES: 0x1242bc0 RPRO: 0
RSET: 0x7f5fc3ca6560 SCAN: 1 second SDIS:CONSTANT
SEVR: NO_ALARM SIML:CONSTANT SIMM: NO SIMS: NO_ALARM
SIOL:CONSTANT SPVT: 0x1558ce0 STAT: NO_ALARM SVAL:
TIME: 2021-06-16 14:47:16.997443401 TPRO: 0 TSE: 0
TSEL:CONSTANT UDF: 1 UDFS: INVALID
VAL: Sun, 07 Feb 2106 06:28:16
The SCAN field is 1s, VAL field never changes but the TIME field of the PV does.
That explains why your source record isn’t getting a new timestamp then; the TSEL link actually sets up a CA monitor on the VAL field, so if that monitor never updates it will never get a new timestamp value.
If you set the MPST field of the above record to “Always” it will cause every process to generate a monitor update, which will update your other records.
