Recently a client called asking what I thought would be the best PLC to replace a Fixed SLC-500. Specifically he was looking to replace a 1747-L40A. To pick a replacement we first needed to understand what this part number represents, and we covered this in detail in our last article. We found that the 1747-L40A consisted of (24) 120VAC inputs, (16) AC/DC relay outputs, and was powered by 120VAC or 240VAC. With the these details in hand we can now go about choosing a modern PLC replacement for the 1747-L40A. When replacing a Fixed SLC-500, I typically recommend a MicroLogix as the replacement for these two reasons: • The MicroLogix is based on the SLC-500, and therefore the majority of code written for the Fixed SLC-500 will import directly into the MicroLogix. • The programming software for the SLC-500 is the same programming software used for the MicroLogix, however an updated version may be needed if the client's existing RSLogix500 is older than the chosen MicroLogix replacement.
If the client's RSLogix500 is too old to program the selected MicroLogix replacement, we'll need to know if the client has a Rockwell support contract in place. If he does, he's entitled to free updates and can download the latest version of RSLogix 500 that supports the latest SLC-500's and MicroLogixs. However, if the client doesn't have a support contract the least expensive option would be for him to purchase a new copy of the RSLogix Micro Starter programming software, which is roughly $165.00. RSLogix Micro Starter looks and feels identical to RSLogix 500, but it limited to the MicroLogix family. Note: If the client were to choose a MicroLogix 1000 or 1100, he could use the free RSLogix Micro Starter Lite software – more about that. With programming software and conversion discussed, it's now time to pick an actual hardware replacement with (24) 120VAC inputs, (16) AC/DC relay outputs.
Nov 12, 2017 - Overview Allen-Bradley 2707-M232P3 DTAM Micro Operator Interface, RS-232 Mfr. Part Number: 2707-M232P3 Manufacturer: Allen-Bradley.
As we have already identified the MicroLogix as the most likely candidate, we'll reference the Allen-Bradley (A-B) MicroLogix Selection guide. On page 58 of this selection guide we find the MicroLogix 1762-L40AWA also has (24) 120VAC inputs, (16) relay outputs, and is powered by 120VAC or 240VAC. This is identicle to the L40A we need to replace, but we need to be sure the relay's have the same rating. On page 61 of the selection guide we find the relay rating chart, and it shows the relay outputs of the 17620L40AWA do have the exact same rating as the relay outputs on the 1747-L40A (found on page 1-8 of it's user manual.) So from an I/O and power standpoint, this model is an exact fit. Download linuxcbt awk-sed edition.iso software engineering. As far the size of the MicroLogix 1200, it's 90mm (height) x 160mm (width) x 87mm (depth) dimensions is substantially smaller than the 1747-L40A's 140mm (height) x 260mm (width) x 145mm (depth.) The last item to consider is the communications port.
