Reading multiple Timers #68

Closed AndrewStuhr closed 4 years ago

AndrewStuhr commented 4 years ago

Hello. I'm not a PLC programmer, so the following terminology may be incorrect.

I'm able to read multiple words inside some registers. For example, I can read F11:0 through F11:9 by using:
c.read_tag('F11:0', 10).

However, I'm unable to do the same with timers. The following returns an error: c.read_tag('T4:0', 10)

I can read individual elements of a timer, such as: c.read_tag('T4:0.PRE')

Is there a way to read multiple timers in a single read request? Thanks!

Andrew, timer like counter are complex objects holding more than one value. Unfortunately I couldn't find a way to read all the information in one shot nor there was any documentation available
